Participants

Reaction Steps

1-Cyclohexyl-5-methylpyrazole-4-carboxylic acid (1.2 g), 5-amino-2-neopentyloxybenzonitrile (1.1 g), triethylamine (1.7 g) and diethyl cyanophosphate (1.4 g) were added to dimethylformamide (15 ml) and the mixture was stirred at room temperature for 1 h. The reaction mixture was added into water and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, after which the solvent was evaporated under reduced pressure. Methanol was added to the residue to allow crystallization. The crystals were recrystallized from hydrous dimethylformamide to give the title compound (1.2 g), melting point: 126–128° C.
