反応手順
To a suspension of compound 17A (1.4 g, 6.76 mmol) and K2CO3 (1.4 g, 10 mmol) in DMF (60 mL) was added iodomethane (0.46 mL, 7.44 mmol). After the addition, the mixture was stirred at 40° C. overnight, then cooled to rt, partitioned between ether and water. The separated ether layer was washed with water and brine, then dried (Na2SO4) and concentrated under reduced pressure. The residue was chromatographed (silica gel) eluting with 10% EtOAc/hexane to yield the title compound (1.38 g, 92% yield).
