Example B22 To a stirring suspension of 6-aminobenzothiazole (0.500 g, 3.33 mmol) in cone. HCl (5 ml) at 0-5 C. was added a solution of NaNO2 (0.276 g, 3.99 mmol) in H2O (5 ml). The mixture was stirred at 0-5 C. for 75 min until a clear yellow solution was obtained. To this was then added a solution of SnCl2.2H2O (2.76 g, 13.3 mmol) in conc. HCl (5 ml). After completing the addition, the suspension was stirred at RT for 2 h. 4-Methyl-3-oxopentanenitrile (0.444 g, 3.99 mmol) and EtOH (50 ml) were added and the reaction was stirred with heating at 75 C. After 18 h, the completed reaction was cooled to RT and concentrated to an aqueous residue. This was chilled thoroughly in ice and made strongly basic (pH 12-13) by the addition of 6M NaOH. While still cold the mixture was extracted with EtOAc (2*). The combined organics were washed with H2O (2*), brine (1*), dried (MgSO4), filtered and evaporated to afford crude 1-(benzo[d]thiazol-6-yl)-3-isopropyl-1H-pyrazol-5-amine (0.8 g, 93% yield) as an oil which was used as is in the next reaction. 1H NMR (400 MHz, DMSO-d6) delta 9.36 (s, 1H), 8.30 (d, J=2.4 Hz, 1H); 8.10 (d, J=8.8 Hz, 1H), 7.74 (dd, J=2.4 and 8.8 Hz, 1H), 5.36 (s, 1H), 5.33 (brs, 2H), 2.76 (septet, J=6.8 Hz, 1H), 1.17 (d, J=6.8 Hz, 6H); MS (ESI) m/z: 259.0 (M+H+).

Sodium hydride (60%, 11.52 g, 287 mmol) in a round bottomflask was cooled using an ice-water bath and kept under nitrogenatmosphere on a Schlenk line. Anhydrous acetonitrile (15.0 mL,287 mmol) and 9.0 mL of anhydrous DMSO were added to the flaskand the mixture was stirred for 30 min. Methyl isobutyrate(33.0 mL, 29.3 g, 287 mmol) was added to the reaction mixture.After stirring for approximately 2 h, the reaction mixture turnedinto a thick white solid. The excess NaH in the reaction mixturewas quenched by slow addition of deionized water. NH4Cl(30.7 g) was added to fully protonate the product, which immediatelygave a milky white suspension. The product was thenextracted three times (150 mL each) with ethyl acetate. All organiclayers were combined and washed with NaCl brine. The organiclayer was dried over anhydrous MgSO4 and filtered. To this solutionwas added 16.0 ml (13.1 g, 110 mmol) of DMF-DMA and thereaction was stirred for 18 h, after which the solvent was removedunder reduced pressure and the product (2-isobutyryl-3-dimethylaminoacrylonitrile) purified by column chromatographyusing CHCl3 as the mobile phase. The solvent was removed andthe product dissolved in 50 mL of methanol. Hydrazine hydrate(8.0 mL, 78 mmol) was added and the reaction stirred overnight.Solvent was removed under reduced pressure and the productpurified by column chromatography using 50:50 ethyl acetate/hexanes to give 2e as a light yellow powder (5.86 g, 43.4 mmol,15% yield based on acetonitrile).

Hydroxylamine hydrochloride (10.3 g, 148 mmol) was slowly added to an ice cold solution of NaOH (25.9 g, 645 mmol) in water (73 mL) and the resulting solution was poured into a solution of crude 3-oxo-4-methylpentanenitrile while stirring. The resulting yellow solution was heated at 50 C for 2.5 hours to produce a less dense yellow oil. The warm reaction mixture was immediately extracted with CHCl3 (3 x 100 mL) without cooling. The combined organic layers were dried (MgSO4), and concentrated in vacuo. The resulting oily yellow solid was filtered through a pad of silica (10% acetone/90% CH2Cl2) to afford the desired isoxazole as a yellow solid (11.3 g, 70%): mp 63-65 C; TLC Rf (5% acetone/95% CH2Cl2) 0.19; 1H-NMR (DMSO-d6) d 1.12 (d, J=7.0 Hz, 6H), 2.72 (sept,J=7.0 Hz, 1H), 4.80 (s, 2H), 6.44 (s, 1H); FAB-MS m/z (rel abundance) 127 ((M+H)+; 67%).
