실험 절차

A mixture of 4-bromomethyl-2-(4-chloro-phenyl)-thiazole-5-carboxylic acid ethyl ester (2.22 g, 6.18 mmol), tert-butoxycarbonylamino-acetic acid ethyl ester (1.32 g, 6.48 mmol) and sodium hydride (60% in mineral oil, 296 mg, 7.4 mmol) in anhydrous dimethylformamide (30 mL) was stirred at 0° C. for one hour and room temperature for four hours before it was quenched with brine. The mixture was partitioned between ethyl acetate and water. The organic layer was washed with water, brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel with a gradient of ethyl acetate and hexanes to give the title compound as a yellow oil (964 mg): 1H NMR (CDCl3, 200 MHz): δ=7.87 (d, 2H), 7.39 (d, 2H), 4.99 (m, 2H), 4.21 (m, 6H), 1.45 (s, 9H), 1.26 (t, 3H).
