Participants

Reaction Steps

N-methylmorpholine (186 mg, 1.84 mmol) was added to an ambient temperature solution of 2-{[(benzyloxy)carbonyl]amino}-3-[4-(5-fluoropyridin-2-yl)phenyl]-2-methylpropanoic acid (150 mg, 0.37 mmol), 1-amino-4,4-dimethylhexan-2-ol (214 mg, 1.48 mmol), 1-[3-(dimethylamino) propyl]-3-ethylcarbodiimide hydrochloride (84 mg, 0.44 mmol), and 1-hydroxybenzotriazole (67 mg, 0.44 mmol) in methylene chloride (5 mL). After stirring at ambient temperature overnight, the reaction mixture was poured into ethyl acetate and washed successively with saturated aqueous sodium bicarbonate and brine, dried (sodium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 40-80% ethyl acetate/hexane afforded benzyl {1-[4-(5-fluoropyridin-2-yl)benzyl]-2-[(2-hydroxy-4,4-dimethylhexyl)amino]-1-methyl-2-oxoethyl}carbamate.
