実験手順

A solution of 5-[2-(methylthio)ethoxy]pyrimidin-2-amine (1.03 g, 5.55 mmol) obtained in Step 1 and 3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypicolinaldehyde (1.60 g, 6.10 mmol) obtained in Step 3 in 1,2-dichloroethane (60 mL) was stirred at room temperature for 10 minutes, and then added with sodium triacetoxyborohydride (1.24 g, 5.83 mmol), and the mixture was stirred at room temperature for 12 hours. The reaction mixture was added with water, and extracted with chloroform— The organic layers were combined, washed with water and saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain N-({3-[(cyclopentylmethyl)(ethyl)amino]-6-methoxypyridin-2-yl}methyl)-5-[2-(methylthio)ethoxy]pyrimidin-2-amine (1.60 g, 67%) as pale yellow oil.
