Reaction Conditions

Reaction Steps

To a stirred solution of (23) (50 mg, 0.108 mmol) in methanol (5 mL) and water (5 mL) was added potassium carbonate (29 mg, 0.216 mmol). The RM was heated to 60° C. overnight. After completion of the SM, the solvents were completely distilled off and diluted with water and extracted with chloroform twice. The organic layer was dried over sodium sulphate and completely distilled off to get the crude product, which was passed through 100-200 mesh silica gel eluting the pre compound at 28-30% ethyl acetate in hexane as eluent to get the pale yellow colored solid (24). 1H NMR (CDCl3) δ: 11.05 (1H), 8.57 (d, J=4.75 1H), 7.50 (m, J=5.85 1H), 7.48 (m, J=5.73 1H), 7.16 (m, J=4.87 1H), 7.12 (m, J=3.17 1H), 6.98 (m, J=4.87 3H), 6.61 (d, J=8.17 1H), 3.21 (3H) and MS m/z=308.1.
