Participants

Reaction Steps

18.5 g of (4-bromo-6-((methoxymethyl)(1,3-thiazol-2-yl)amino)pyridin-2-yl)-methanol was dissolved in 110 mL of dimethylformamide and 9.64 g of imidazole was added thereto. Under cooling with an ice bath, 10.2 g of tert-butyldimethylsilyl chloride was added thereto followed by stirring at room temperature for 3 hours. The reaction solution was diluted with ethyl acetate and washed with water and brine. The resulting organic layer was dried over magnesium sulfate and filtered, and the filtrate was concentrated. The resulting residue was purified by a silica gel column chromatography (eluent: hexane/ethyl acetate=9/1 to 4/1) to give the title compound.
