Participants

Reaction Steps

10.84 g (33.43 mmol; 92% purity) of rac-2-[(diphenylmethylene)amino]-4,4-difluoro-2-methylbutanonitrile from Example 70A were dissolved in 156 ml of tetrahydrofuran and 6 ml of water, 73.5 ml (36.77 mmol) of hydrogen chloride solution (0.5 N in diethyl ether) were added and the mixture was stirred at room temperature overnight. The reaction solution was admixed with 16.71 ml (33.43 mmol) of hydrogen chloride solution (2 N in diethyl ether) and concentrated by rotary evaporation. The isolated crude product was reacted further directly without further purification.
