Participants

Reaction Steps

To a solution of (R)-1-methylpyrrolidin-3-yl 2-(tert-butoxycarbonylamino)-2-phenylacetate (C61) (170 mg, 0.51 mmol) in DMF (5 ml) and acetonitrile (3 ml), was added 2-bromo-1-phenylethanone (111 mg, 0.56 mmol). The reaction was stirred at RT for 15 hours, and the solvent was evaporated. The crude was purified by flash chromatography (DCM/MeOH=9/1) to obtain (3R)-3-(2-(tert-butoxycarbonylamino)-2-phenylacetoxy)-1-methyl-1-(2-oxo-2-phenylethyl)pyrrolidinium bromide (152 mg; 56% yield).
