실험 절차

A mixture of benzyl 2-[3,5-dichloro-2-methyl-6-oxo-1(6H)-pyrazinyl]acetate (preparation 17) (400 mg, 1.22 mmol) and [(2S)-1-(cyclopropylmethyl)pyrrolidinyl]methylamine (WO 87,07271) (190 mg, 1.22 mmol) and triethylamine (0.51 ml, 3.67 mmol) in ethyl acetate (20 ml) was heated under reflux for 18 hrs. The cooled mixture was partitioned between water and ethyl acetate, the phases separated, and the organic layer dried over MgSO4 and concentrated under reduced pressure. The residual orange oil was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (96:3.5:0.5) as eluant to give the desired product as a yellow oil, (476 mg, 88%).
