Procedure

A mixture of N-{1-[2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)-6-methylquinolin-4-yl]-3-methylpyrrolidin-3-yl}acetamide (102 mg, 0.21 mmol) and hydrochloric acid (2 N, 120 mL) was heated with stirring at 100° C. for 16 hours. After being cooled to room temperature, the reaction mixture was adjusted to pH 9 with a saturated aqueous solution of potassium carbonate and exacted with dichloromethane (200 mL×3). The combined organic layers were dried over sodium sulfate, and concentrated in vacuo. The residue was purified by preparative HPLC to afford 2.6 mg of the product (yield was 2.8%). MS obsd.
