Reaction Steps

Cesium carbonate (735 mg, 0.0022 moles) was added to a solution of (2-(1-(pyrimidin-2-yl)piperidin-4-yl)thiazol-4-yl)methyl methanesulfonate (490 gm, 0.00112 moles) and 4-(2,2-dimethyl-1,3-dioxan-5-yl)phenol (281 mg, 0.001384 moles) in DMF (10 ml) and the reaction mixture was stirred at 60° C. for 2 hours. Then the reaction mixture was then poured into ice cold water and extracted with ethyl acetate. The organic extract was successively washed with water & brine, dried over sodium sulfate and concentrated under reduced pressure. The crude product so obtained was purified by column chromatography (silica gel) using 22% ethyl acetate in hexane as eluent to obtain 600 mg product as white solid.
