Reaction Steps
3-(Methylamino)-1-(methanesulfonyl)pyrrolidine was prepared from 3-(methylamino)-1-benzylpyrrolidine after four steps: i) (Boc)2O, MeOH, rt; ii) H2 (1 atm), 10% Pd/C, EtOH; iii) CH3SO2Cl, i-Pr2NEt, CH2Cl2; iv) CF3CO2H, CH2Cl2. (m/z): [M+H]+ calcd for C6H14N2O2S: 179.08; found, 179.2. 3R-Methylamino-1-(methanesulfonyl)pyrrolidine was prepared in a similar manner from (3R)-(methylamino)-1-benzylpyrrolidine.
