Reaction Steps

Methanesulfonyl chloride (51.3 mg, 0.448 mmol) was added to a solution of (2R,4R)-tert-butyl 4-(2,3-dihydrobenzo[b][1,4]dioxine-6-carboxamido)-2-(1-(2-hydroxyethyl)-1H-benzo[d]imidazol-2-yl)piperidine-1-carboxylate (78 mg, 0.15 mmol) and DMAP (3.5 mg) in pyridine (1 mL) at 0° C. and the resulting mixture was stirred at room temperature for 5 hours. Water and ethyl acetate were added to the reaction mixture. The organic layer was separated and dried over MgSO4 and concentrated to give a yellow solid, which was purified by Companion (ReadSep, 12 g, silica gel packed) with ethyl acetate/heptane from 30-70% to give title compound as a white solid 65 mg (73%). LC-MS: 601.1 (t=2.6 min).
