Reaction Steps
N,N-Diisopropylethylamine (1.0 mL, 5.74 mmol) was added to a mixture of (2S)-2-[(tert-butoxycarbonyl)amino]-3-methylbutanoic acid (0.217 g, 1.0 mmol), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.211 g, 1.1 mmol) and dimethylamine in THF (2M, 1.0 mL) in methylene chloride (10 mL). The mixture was stirred overnight at RT. The mixture was washed with water, saturated NaHCO3 solution, brine, dried over Na2SO4, filtered, and concentrated. The residue was chromatographed on silica gel to give the desired product (131 mg, 53.6%).
