Reaction Steps
To a solution of tert-butyl thiazol-4-ylcarbamate (13.0 g, 64.9 mmol) in DMF (150 mL) was added Cs2CO3 (42.3 g, 130 mmol) and 1-(chloromethyl)-4-methoxybenzene (12.1 g, 78.0 mmol, Spectrochem). The reaction mixture was stirred at 80° C. for 6 h. The reaction mixture was allowed to cool to room temperature and water (500 mL) was added. The aqueous layer was extracted with diethyl ether (2×500 mL). The combined organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to obtain the crude material which was further purified by column chromatography (silica gel 100-200 mesh and 0-20% ethyl acetate in hexanes) to obtain tert-butyl 4-methoxybenzyl(thiazol-4-yl)carbamate (15.0 g, 80%) as an off-white solid. MS (ESI, positive ion) m/z=321 (M+1)+.
