A 10 mL microwave tube was charged with 5-bromo-2-chloro-7H-pyrrolo[2,3-d]pyrimidine (0.23 g, 1.0 mmol), tert-butyl trans-4-(iodomethyl)cyclohexylcarbamate (0.51 g, 1.5 mmol), K2CO3 (0.28 g, 2.0 mmol), DMSO (1.5 mL) and THF (3 mL). The mixture was heated at 150° C. for 100 min in microwave. After the reaction mixture was cooled to ambient temperature, n-butylamine (0.18 g, 2.5 mmol) was added. The mixture was heated at 150° C. for 90 min in microwave. After cooling to ambient temperature, the reaction was poured into water and extracted with EtOAc (3×). The combined organic layer was dried (Na2SO4) and concentrated. The crude mixture was purified by Isco to provide tert-butyl trans-4-((5-bromo-2-(butylamino)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)methyl)cyclohexylcarbamate (0.35 g, 73%) as a white solid. MS m/z 480.2 [M+H]+.
