YieldReaction ConditionsOperation in experiment
47% Compound 2 (0.50 g, 2.9 mmol) in anhydrous acetone (15 mL) was added at 0 C to a flask containing potassium carbonate (0.80 g, 5.8 mmol) in anhydrous acetone (2.5 mL). After stirring for 1 h at 0 C, allyl bromide (0.28 mL, 4.0 mmol) and tetrabutyl ammonium iodide (0.21 g, 0.58 mmol) were added and the reaction mixture was stirred for 15 h at 25 C. Acetone was evaporated and the mixture was dissolved in ethyl acetate (20 mL) followed by successively washing with water (3 x 10 mL), brine (10 mL), drying over magnesium sulfate and concentration in vacuo. The crude compound was purified by silica gel flash column chromatography (cyclohexane : ethyl acetate; 8 : 2) to give a white powder (0.67 g, 47%). NMR (CDCI3) ö 10.39 (5, 1 H), 7.32 (d, J= 3.2 Hz, 1H), 7.11 (dd, J= 9.2, 3.2 Hz, 1H), 6.92 (d, J= 9.2 Hz, 1H), 6.10-6.00 (m, 1H), 5.45-5.38 (m, 1H), 5.32-5.27 (m, 1H), 4.52-4.48 (m, 2H), 3.95 (5, 3H); 13C NMR (CDCI3) ö170.2, 156.1, 150.8, 133.1, 124.6, 118.4, 117.7, 113.1, 111.7, 69.5, 52.3; HRMS (ESI):[M+NH4] calcd. for C12H18N04 240.1230, found 240.1229.
