Reaction Steps

Cyclohexyl(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)methanamine (10 mg. 0.028 mmol) in N,N-dimethylformamide dimethyl acetal (0.7 mL) was stirred at 170° C. for 30 minutes under microwave irradiation. The reaction mixture was allowed to cool to room temperature and concentrated under reduced pressure, and the resulting residue was dissolved in 1,3-dimethylimidazolidin-2-one (1.0 mL) and stirred at 230° C. for 1.5 hours under microwave irradiation. Separately, cyclohexyl(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-ylmethanamine (89 mg, 0.25 mmol) in N,N-dimethylformamide dimethyl acetal (1 mL) was stirred at 170° C. for 30 minutes under microwave irradiation. The reaction mixture was allowed to cool to room temperature and concentrated under reduced pressure, and the resulting residue was dissolved in 1,3-dimethylimidazolidin-2-one (4.5 mL) and stirred at 230° C. for 1.5 hours under microwave irradiation. The reaction mixture and the previously obtained reaction mixture were combined, diluted with ethyl acetate, acidified with 1 M hydrochloric acid and washed with saturated aqueous ammonium chloride and saturated aqueous sodium chloride, and the organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel thin layer chromatography (hexane/ethyl acetate=2/1→1/1→1/2 (v/v)) to give the title compound as a pale yellow oil (31.4 mg, yield 30%).
