Reaction Steps

To a solution of Example 171G (0.15 g, 0.22 mmol) in methanol (2 mL) was added K2CO3 (68 mg, 0.5 mmol). The resulting mixture was stirred at r.t. for 3 hrs, and then poured into N HCl (10 mL), extracted with ethyl acetate (3× 10 mL), and the combined organic layers were dried over Na2SO4. The crude product was purified by column chromatography on silica gel using 5% methanol in chloroform, and the title compound was obtained as a lt. yellow solid (0.134 g, 97%). 1H NMR (300 MHz, DMSO-d6): δ 0.45 (m, 1H), 0.63 (d, J=6.62 Hz, 3H), 0.69 (d, J=6.62 Hz, 3H), 0.94 (m, 1H), 1.27 (m, 1H), 1.61 (m, 3H), 1.99 (m, 1H), 2.23 (m, 2H), 2.89 (m, 1H), 3.03 (s, 3H), 3.20 (m, 1H), 3.65 (dd, J=9.93, 3.68 Hz, 1H), 3.98 (m, 1H), 7.13 (m, 1H), 7.52 (m, 5H), 8.11 (m, 1H), 10.07 (br s, 1H), 14.18 (br s, 1H); MS (ESI) m/z=631 [M+H].
