실험 절차

Under ice-cooling, ethyl 2-[3-[(4-tert-butyl-2-thiazolyl)methoxy]benzoylamino]-4-[3-(4-chlorophenylsulfonyl)propyl]phenoxyacetate (266 mg, 0.39 mmol) was added to a mixture of 60% sodium hydride (19 mg, 0.48 mmol) and dimethylformamide (2 ml), and the reaction solution was stirred at room temperature for 1 hour. The reaction solution was again cooled with ice, methyl iodide (29 μl, 0.47 mmol) was added, and the mixture was stirred at room temperature for 2 hours. Water was added to the reaction solution and the product formed was extracted with toluene. The extract was washed with water and brine in that order, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. Thereafter, the resulting residue was purified by silica gel column chromatography (eluent=chloroform:methanol=50:1) to give ethyl 2-[N-[3-[(4-tert-butyl-2-thiazolyl)methoxy]benzoyl]-N-methylamino]-4-[3-(4-chlorophenylsulfonyl)propyl]phenoxyacetate (213 mg, 0.31 mmol, 78%).
