실험 절차
The title compound was prepared by a similar method to preparation 42 from benzyl 2-[3,5-dichloro-2-methyl-6-oxo-1(6H)-pyrazinyl]acetate (preperation 17) and tert-butyl (2R)-2-(aminomethyl)-1-pyrrolidinecarboxylate [see preparation 52]. The crude product was purified by column chromatography on silica gel using an elution gradient of ethyl acetate:pentane (10:90) changing to (80:20) in 10% increments to afford the title compound as a clear oil, (80%).
