A mixture of 3-(4-chloro-7H-pyrrolo[2,3-d]pyrimidin-5-yl)benzonitrile (C14) (157 mg, 0.616 mmol), dimethylamine (189 mg, 4.19 mmol) and triethylamine (182 mg, 1.80 mmol) in n-butanol (12 mL) was heated under microwave irradiation at 150° C. for 25 minutes. After concentration in vacuo, the residue was purified by preparative HPLC (Column: Phenomenex Gemini C18, 8 μm; Mobile phase A: ammonia in water, pH 10; Mobile phase B: acetonitrile; Gradient: 25% to 65% B) to give the product as a white solid. Yield: 72.1 mg, 0.274 mmol, 44%. LCMS m/z 263.8 [M+H+]. 1H NMR (400 MHz, DMSO-d6) δ 12.15 (br s, 1H), 8.28 (s, 1H), 7.93 (br s, 1H), 7.78 (br d, J=7.8 Hz, 1H), 7.73 (br d, J=7.8 Hz, 1H), 7.62 (br dd, J=8.0, 7.8 Hz, 1H), 7.57 (br s, 1H), 2.73 (s, 6H).
