Reaction Steps

Trimethylsilyl cyanide (0.532 ml, 4.0 mmol) was added dropwise to the mixture of 3-amino-5-methylpyrazole (0.194 g, 2.0 mmol) and cyclobutanone (0.154 g, 2.2 mmol). The reaction mixture was stirred at room temperature for 40 h and then concentrated under vacuum to obtain a dark liquid which was subjected to chromatography (dichloromethane) to yield 16a (0.267 g, 1.52 mmol, 76%) as a off-white powder.
