実験手順

Neopentylchloroformate (28 uL, 0.186 mmol) 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 pyridine (1 mL) and dichloromethane (1 mL) under nitrogen at 0° C. After 10 minutes, the ice water bath was removed and the resulting mixture was stirred for 4 hours. The solvent was evaporated and the residue was taken into ethyl acetate. The organic layer was washed, dried and evaporated. The solid was purified by preparative TLC using dichloromethane/methanol (95:5) as the mobile phase to give neopentyl N-[4-(4-amino-7-cyclopentyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-2-methoxyphenyl]carbamate. 1H NMR (CDCl3) δ 1.00 (s 9H), 1.78 (m, 2H), 1.90 (m, 4H), 2.26 (m, 2H), 3.91 (s, 2H), 3.94 (s, 3H), 5.22 (m, 3H), 6.22 (s, 1H), 7.01 (s, 1H), 7.08 (d, J=8 Hz, 1H), 7.25 (s, 1H), 8.17 (br. d, 1H), 8.32 (s, 1H); LC/MS (MH+=438).
