Reaction Steps

A solution of {6-[4-(2-hydroxymethyl-pyrrolidine-1-sulfonyl)-phenyl]pyridin-2-yl}carbamic acid tert-butyl ester (15.0 g, 34.6 mmol) in HCl/MeOH (50 mL, 2M) was heated at reflux for 2 h. After cooling to room temperature, the reaction mixture was evaporated under vacuum and washed with EtOAc to give (R)-(1-(4-(6-aminopyridin-2-yl)phenylsulfonyl)pyrrolidin-2-yl)methanol hydrochloride (C-2; 11.0 g, 86%). 1H NMR (300 MHz, DMSO-d6) δ 8.18 (d, J=8.7 Hz, 2H), 7.93-7.99 (m, 3H), 7.31 (d, J=7.2 Hz, 1H), 7.03 (d, J=8.7 Hz, 1H), 3.53-3.57 (m, 2H), 3.29-35 (m, 2H), 3.05-3.13 (m, 1H), 1.77-1.78 (m, 2H), 1.40-1.45 (m, 2H). MS (ESI) m/z (M+H)+ 334.2.
