반응 단계
A mixture of 5.35 g (30 mmol) of 2-amino-3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophene (prepared according to Intermediate 1e), 2.0 ml (45 mmol) of triethylamine, 10 ml (90 mmol) of n-butyl isocyanate and 100 ml of toluene was stirred for 16 hours at 80° C. The solid formed was then isolated and was recrystallized from ethanol. Yield: 18%; mp.: 170°-171° C.
