실험 절차
0.34 g of N-methylpiperidine was added to a solution containing 0.7 g of N-isopropoxycarbonyl-L-valine dissolved in 50 ml of methylene chloride, at -20° C. After the mixture was stirred for 10 minutes at the same temperature, 0.47 g of isobutyl chloroformate was added to the mixture, and stirred for 1 hour at -20° C. 0.74 g of 1-(5-chloro-6-ethyl-4-pyrimidinyloxy)-2-propylamine was added to this mixture at -60° C., and then the reaction mixture was allowed to sit and warm naturally to room temperature while being stirred, and was stirred for 20 hours at room temperature. Water was subsequently added to the reaction mixture. After the methylene chloride layer was washed successively with a 5% aqueous solution of sodium bicarbonate and water, the organic layer was dried over anhydrous magnesium sulfate and the methylene chloride was removed under reduced pressure. The obtained crude crystal was purified by column chromatography on silica gel, thus obtaining 0.6 g of the desired product in the form of a white prism-shaped crystal (yield: 43%).
