Trimethylsilyl cyanide (0.146 ml, 1.1 mmol) was added dropwise to the mixture of p-toluidine (0.107 g, 1 mmol) and fluoroacetone (0.082 g, 1.1 mmol). The reaction mixture was stirred at room temperature for 12 h and then concentrated under vacuum to obtain a brown liquid which was subjected to chromatography (dichloromethane) to yield 19a (0.179 g, 0.93 mmol, 93%) as a yellowish solid.
