实验过程

The [1-methyl-4-(trifluoromethyl)-1H-pyrazol-3-yl]acetonitrile (4.76 mmol, 0.90 g), the di-terbutyl carbonate (9.52 mmol, 2.08 g) and nickel chloride hexahydrate (4.77 mmol, 1.13 g) are added to methanol (10 ml) at room temperature. Sodium borohydride (13.1 mmol, 0.49 g). is added portionwise to the reaction mixture. The reaction mixture is allowed to room temperature and stirred for three hours.
