Reaction Steps

Diisopropylethylamine (730 μl, 4.2 mmol) was added to a mixture of 2-(methylsulfonyl)-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (330 mg, 2.1 mmol) and 1-(6-chloropyridin-3-yl)ethanamine (described in the literature: EP 375907 (B1)) (500 mg, 1 mmol) in tetrahydrofuran (3 mL). The reaction mixture was heated under microwave irradiation at 110° C. for 15 minutes. The reaction mixture was partitioned between EtOAc and water. The organic phase was dried over magnesium sulphate, filtered and evaporated to dryness. The residue was purified on silica gel by flash column chromatography to afford the title compound as a wax (345 mg, 58% yield).
