Reaction Steps

To a suspension of 5-(2-bromo-pyridin-4-yl)-5-hydroxymethyl-morpholin-3-one (3.25 g, 11.0 mmol), Na2CO3 (3.5 g, 13.06 mmol) in dry THF (15 ml) was added diethylaminosulfur trifluoride (2.25 ml, 17.0 mmol) at 0° C. The reaction mixture was allowed to warm to rt and stirred for 2 h. Solid Na2CO3 (3.5 g) was again added to the reaction mixture and stirred for 4 h at rt. Solids present in the reaction mixture filtered through Buchner funnel. Filtrate was concentrated under reduced pressure and the crude product was purified by column chromatography using 5% methanol in DCM to obtain title compound as a pale yellow solid. Yield=2.1 g (66%). TLC (50% ethyl acetate in hexane) Rf=0.17; LCMS: RtH7=0.201; [M+1]+=289 and 291; HPLC: RtH9=5.171 min. (50%) and 5.063 (21%).
