Procedure

To (S)-2-(tert-butoxycarbonyl(methyl)amino)-4-methylpentanoic acid in DMF was added EDC, DMAP and isoquinolin-7-amine. This mixture was stirred for 4 hours and the reaction was washed with NaHCO3 (sat), extracted with EtOAc, dried (Na2SO4), filtered and evaporated. Column chromatography (SiO2, Hexanes/EtOAc) gave pure (S)-tert-butyl 1-(isoquinolin-7-ylamino)-4-methyl-1-oxopentan-2-yl(methyl)carbamate (E87).
