Procedure

To a solution of 14.28 g of 6-(((tert-butyl(dimethyl)silyl)oxy)methyl)-N-((2Z)-3-(methoxymethyl)-1,3-thiazol-2(3H)-ylidene)pyridin-2-amine in 30 ml of chloroform and 30 ml of methanol was added 30 ml of trifluoroacetic acid under cooling with ice, followed by stirring the reaction mixture at room temperature overnight. The reaction mixture was evaporated in vacuo. The resulting residue was neutralized with saturated aqueous sodium bicarbonate solution and extracted with ethyl acetate. The resulting ethyl acetate solution was dried over anhydrous magnesium sulfate and filtered. The filtrate was concentrated in vacuo. The resulting residue was purified by a silica gel column chromatography (eluent: hexane to hexane/ethyl acetate =1/1) to give the title compound as a pale yellow solid.
