실험 절차

The standard procedure was followed using N-(4-cyano-2-t-butyldimethylsilanoxyphenyl)-N′-(2-bromophenyl)carbodiimide (106 mg, 0.25 mmol), diisopropylethylamine (71 μL, 0.28 mmol), methyl pipecolinate hydro chloride (50 mg, 0.28 mmol) and TBAF (0.30 mL, 0.30 mmol) in THF (2.5 mL) and methanol (0.1 mL) to give 80 mg (75%) of 4-[[2-(2-bromophenyl)-1,5,6,7,8,8a-hexahydro-1-oxoimidazo[1,5-a]pyridin-3(2H)-ylidene]amino]-3-hydroxybenzonitrile as a tan powder. MS (EI) m/e 425 (100(M+)).
