Electric Literature of 96606-37-0, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 96606-37-0 as follows.
2,4,6-trifluorobenzonitrile (100 mg, 64 mmol), phenol (120 mg, 1.2 mmol) and potassium carbonate (87 mg, 64 mmol) were irradiated in the microwave in NMP (3 mL) at 120C for 10 minutes at which point LCMS indicated that the reaction was complete. Guanidine carbonate (231 mg, 1.91 mmol) was added and the reaction irradiated in the microwave at 150C for 15 minutes. The mixture was cooled and purified directly by reversed phase HPLC (15 to 95% ACN in DI water containing 0.1% TFA: 15 minute gradient). The pure fractions were pooled and concentrated to afford the product as an off white solid.135 mg, 61% yield, 2 steps.1H-NMR (300 MHz, DMSO d6) delta 12.68 (s, 1H), 8.93 (s, 1H), 8.40 (bs, 2H), 7.54-7.43 (m, 6H), 7.37-7.28 (m, 2H), 7.15 (d, 2H, J=7.2 Hz), 6.42 (s, 1H), 6.01 (s, 1H). LC/MS [M+H]+ 345.4.
