실험 절차

The same operation as in Example (217a) was performed using 3-tert-butoxycarbonylaminoazetidine (124 mg, 0.72 mmol), methyl 2-bromo-4-ethyl-1,3-thiazole-5-carboxylate obtained in Example (22c) (158 mg, 0.63 mmol) and diisopropylethylamine (0.21 mL, 1.20 mmol), to obtain 143 mg of the title compound as a white solid (66%).
