Adding a certain compound to certain chemical reactions, such as: 76469-88-0, name is Methyl 4-(cyanomethyl)benzoate, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 76469-88-0, Recommanded Product: 76469-88-0
Referential Example 57 Methyl 4-[2-(tert-butoxycarbonylamino)ethyl]benzoate Methyl 4-cyanomethylbenzoate (0.20 g) was dissolved in a mixed solvent of methanol (15 ml) and chloroform (0.4 ml). To the resulting solution, platinum dioxide (33 mg) was added, followed by catalytic reduction at room temperature under 3 atmospheric pressure for 3 hours. The catalyst was removed by filtration through Celite and the solvent was distilled off under reduced pressure. The residue was suspended in dichloromethane (5 ml), followed by the addition of triethylamine (160 mul). After the addition of a solution of di-tert-butyl dicarbonate (0.29 g) in dichloromethane (dichloromethane: 2 ml) under ice cooling, the resulting solution was stirred at room temperature for 13 hours. The reaction mixture was diluted with dichloromethane, washed with water and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure. The residue was purified by chromatography on a silica gel column (hexane:ethyl acetate 10:1~5:1), whereby the title compound (0.28 g, 88%) was obtained. 1H-NMR (CDCl3) delta: 1.43(9H,s), 2.86(2H,t,J=6.8 Hz), 3.39(2H,m), 3.91(3H,s), 4.53(1H,br), 7.27(2H,d,J=8.3 Hz), 7.98(2H,d,J=8.3 Hz).
