A mixture of 62.4 (3.58 mmol) and K2CO3 (0.99 g, 7.16 mmol) in MeOH (18 mL) was stirred for 5 hours at room temperature. The mixture was filtered (DCM) and concentrated, and the crude product was chromatographed on silica gel (0-30% EtOAc/hexane) to afford 62.5 (0.61 g, 82%) as a yellow liquid. 1H NMR (400 MHz, CDCl3) δ 6.78 (s, 1H), 4.68 (s, 2H), 2.18 (s, 3H).
