To a solution of 4-[4-amino-5-(4-amino-3-methoxyphenyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl]-1-cyclohexanone (0.8 g, 2.3 mmol) in pyridine (13 mL) and dichloromethane (32 mL) at 0° C. was added hydrocinnamoylchloride (0.57 g, 3.4 mmol) in dichloromethane (5 mL) under nitrogen. The solution was stirred at 0° C. for 2 hr, warmed to room temperature and quenched by addition of saturated aqueous citric acid solution (50 mL). The organic layer was washed with saturated aqueous citric acid solution (2×50 mL), dried (sodium sulphate), filtered and evaporated to leave N1-{4-[4-amino-7-(4-oxocyclohexyl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]-2-methoxyphenyl}-3-phenylpropanamide (1.0 g, 92% crude) as a brown foam. 1H NMR (d6 DMSO, 400 MHz):9.17(1H, s), 8.18(1H, s), 8.06(1H, d), 7.51(1H, s), 7.18-7.29(6H, m), 7.09(1H, m), 6.99(1H, d), 6.21(2H, bs), 5.18 (1H, m), 3.88(3H, s), 1.99-2.93(12H, m). HPLC: (5 to 95% CH3CN in 0.1 N aqueous ammonium acetate over 20 min.) tr=14.48 min, 92.2%.
