Reaction Steps

Dissolve 3-[(6-nitro-benzothiazol-2-ylamino)-methyl]-pyrrolidine-1-carboxylic acid tert-butyl ester (5.55 g, 14.7 mmol) in DMF (30 mL) and cool to 5° C. Add 60% NaH in mineral oil (1.12 g, 16.13 mmol) and stir for 5 min. Add iodomethane (6.0 mL, 74 mmol) and stir at 5° C. for 30 min. Quench the reaction with water and dilute with ethyl acetate. Wash the organic layer with water (5×20 mL), then wash with brine. Collect the organic layer, dry over Na2SO4, filter, and concentrate in vacuo. Chromatograph (silica gel, eluting with 20-60% Ethyl acetate:Hexane) to yield 1.96 g (34%) of the title compound. mass spectrum (ion-spray): (m/z)=393.3 (M+1).
