Procedure
Intermediate 19 (0.5 g, 1.75 mmol) was dissolved in DCM (10 ml) and reaction mixture cooled to 0° C. To this (Diethylamino)sulphur trifluoride (0.46 ml, 3.5 mmol) was added drop-wise and allowed the reaction mixture to stir at rt for 30 mins. After completion of the reaction, reaction mixture diluted with DCM and washed with water. DCM removed on rotavapour to obtain the crude. Crude was purified by column chromatography using EA and petether (7:97) as eluent to afford the title compound (0.41 g) as an yellow solid. 1H-NMR (δ ppm, CDCl3, 400 MHz): 8.42 (d, J 9, 2H), 7.86 (d, J 9, 2H), 6.94 (d, J 3.4, 1H), 5.42 (d, J 48.4, 2H).
