실험 절차

(2,4-Dichloro-pyrimidin-5-yl-methyl)-(4-ethyl-phenyl)-amine (200 mg, 0.71 mmol) (from Example 38c supra) was dissolved in hot n-butanol (2 mL) (Aldrich). After cooling to room temperature, triethylamine (0.20 mL, 0.92 mmol) (Allied Signal) and (±)-trans-3-(tert-butyl-dimethyl-silanyloxy)-cyclopentylamine (198 mg, 0.91 mmol) (from Example 9c supra) were successively added and the mixture was stirred at room temperature for 18 hours. The mixture was concentrated under reduced pressure and purified by flash chromatography (20% ethyl acetate in hexanes) to give (±)-[trans-3-(tert-butyl-dimethyl-silanyloxy)-cyclopentyl]-{2-chloro-5-[(4-ethyl-phenylamino)-methyl]-pyrimidin-4-yl}-amine as a viscous oil. (Yield 272 mg, 84%).
