실험 절차

200 mg (1.00 mmol) of L-methionine methyl ester hydrochloride was added to a solution of 411 mg (1.00 mmol) of 2-[4-[2-(4-methyl-1-piperazinyl)-4-thiazolyl]phenyl]-3-oxa-1-azaspiro[4.5]dec-1-en-4-one and 258 mg (2.00 mmol) of N,N-diisopropylethylamine in 20 ml of dimethylformamide. After the mixture was stirred at 80° C. for 15 hours, the reaction solution was concentrated under reduced pressure, ethyl acetate was added thereto, and the mixture was successively washed with water, a saturated aqueous sodium hydrogencarbonate solution and saturated brine, followed by drying with anhydrous sodium sulfate. After the solvent was distilled off under reduced pressure, and the residue was purified by silica gel chromatography to obtain 191 mg (33%) of the title compound.
