To a solution of oxo-thiophen-2-yl-acetyl chloride (31.5 mmol) at 0 to 5° C. in chloroform (60 ml) is added a solution of (1-Methyl-piperidin-4-yl)-methanol (4.07 g, 31.5 mmol) in chloroform (60 ml), dropwise maintaining the temperature below 5° C. The resulting mixture is stirred for 2 hours at room temperature. Washing with 10% potassium carbonate solution, water and then drying over magnesium sulphate, filtration and evaporation gives the title compound.
