Procedure

2,2-Dimethyl-propionic acid [(R)-2-(5-chloromethyl-7-nitro-1H-indol-2-yl)-4,5-dihydro-thiazol-4-yl]methyl ester (1.0 g, 2.4 mmol) prepared in Preparation 41 was dissolved in dimethylsulfoxide (15 mL). Diisopropylethylamine (0.6 g, 4.9 mmol) and dimethylamine (0.2 g, 4.9 mmol) were added thereto, and the mixture was stirred for 6 h at room temperature. After completion of the reaction, water was added. The reaction mixture was extracted with ethyl acetate, dried over anhydrous magnesium sulfate, and filtered. The filtrate was distilled under reduced pressure, and purified by column chromatography to give the title compound (0.7 g, Yield 71%).
