Procedure
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 170 and [(2R)-1-isobutylpyrrolidinyl]methanamine [see preparation 60]. The crude product was purified by column chromatography on silica gel using ethyl acetate as the eluant, to afford the product as a yellow oil, (94%).
