Procedure

N-(7-Acetyl-3-(4-isopropylphenyl)-4,6-dimethyl-2,3-dihydro-1-benzofuran-5-yl)formamide obtained in Example 203 (808 mg, 2.3 mmol) was added to a solution of methanol (10 mL) and concentrated hydrochloric acid (5 mL), and the mixture was heated under reflux for 2 hours. The reaction solution was cooled to room temperature and was poured into a cold sodium bicarbonate solution, which was extracted with ethyl acetate. The extract was washed with a saturated brine, dried over sodium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane ethyl acetate=1:1) to obtain the title compound as an oily matter.
