Procedure
A mixture of Example 476D and K2CO3 (7.0 g, 50.6 mmol) in methanol (220 mL) was stirred at room temperature overnight, concentrated under vacuum, diluted with ethyl acetate, washed with water and brine, dried (MgSO4), filtered and concentrated under vacuum to produce 9.7 g (91%) of the desired product. MS (ESI) m/e 315 (M+H)+; 1H NMR (300 MHz, DMSO-d6) □ 7.43 (br s, 2H), 7.37 (s, 1H), 6.66 (s, 1H), 5.28 (s, 2H), 3.69-3.75 (m, 2H), 3.73 (s, 3H), 0.89-0.94 (m, 2H), -0.01 (s, 9H).
