Compound 19 (150 mg, 0.405 mmol) was dissolved in acetonitrile (2 mL) and morpholine (0.282 mL, 3.24 mmol) was added, The solution was sealed and heated to 100° C. for 18 h. The solution was concentrated and the residue was purified by column chromatography on silica gel, eluting with EtOAc/hexane to give the title compound as a colorless oil. 1H NMR (CDCl3) δ 5.13 (s, 1H), 4.52-4.51 (m, 1H), 3.82 (s, 3H), 3.72 (s, 8H), 3.62-3.59 (m, 2H), 3.14-3.10 (m, 2H), 1.94 (m, 1H), 1.72-1.70 (m, 1H), 1.55-1.53 (m, 2H), 1.43 (s, 9H); LCMS 2.02 min, 394 (M+H).
