Procedure

Benzylisocyanate (24 uL, 0.194 mmol) in dichloromethane (1 mL) was added dropwise to a stirring solution of 5-(4-amino-3-methoxyphenyl)-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (50 mg, 0.155 mmol) in N,N-diisopropylethylamine (153 uL, 0.881 mmol) and methylene chloride (2 mL) under nitrogen. The resulting mixture was stirred for 24 hours. The solvent was evaporated and the solid was purified by preparative TLC using dichloromethane/methanol (95:5) as the mobile phase to give N-(4-(4-amino-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methoxyphenyl)-N′-benzylurea. 1H NMR (CDCl3) δ 1.78 (m, 2H), 1.90 (m, 4H), 2.26 (m, 2H), 3.86 (s, 3H), 4.48 (d, J=6 Hz, 3H), 5.24 (m, 4H), 6.93 (s, 1H), 6.98 (s, 1H), 7.00 (s, 1H), 7.04 (d, J=8 Hz, 1H), 7.29 (m, 5H), 8.17 (d, J=8 Hz, 1H), 8.31 (s, 1H); LC/MS (MH+=457).
