Reaction Steps
To a solution of (S)-methyl 2-(2-amino-4-methylpentanamido)acetate hydrochloride (4w) in THF was added 6-((tert-butoxycarbonyl)amino) hexanoic acid, HATU and DIPEA. The reaction was stirred at room temperature for 18 h. The mixture was then filtered through Celite. The filtrate was concentrated under reduced pressure and the crude residue was purified by column chromatography (silica gel, CH2Cl2/MeOH=50/1) to give (S)-methyl 13-isobutyl-2,2-dimethyl-4,11,14-trioxo-3-oxa-5,12,15-triazaheptadecan-17-oate (6w) as a white solid.
