Procedure

To a cooled solution of 1-[2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-yl]pyrrolidine-3-carbonyl chloride (100 mg, 0.21 mmol) in dichloromethane (20 mL) was added a saturated solution of ammonia in dichloromethane (10 mL) slowly at 0° C. After being stirred for 16 hours at room temperature, the mixture was concentrated in vacuo. The residue was purified by preparative HPLC to afford 13 mg of the desired product (yield was 13.5%).
