実験手順

Reaction of the above carbamate (165 mg, 0.282 mmol) with an excess of TFA (2 mL) in CH2Cl2 (10 mL) at room temperature for 1.5 hrs, followed by treatment with aq. NH3 gave 2-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-9-(4-piperidinyl)-9H-purine (121 mg, 88%), which was used in the next step without further purification: 1H NMR (CDCl3) δ 7.87 (s, 1H), 7.81 (dd, J=8.4, 0.5 Hz, 1H), 7.48 (t, J=53.6 Hz, 1H), 7.35 (t, J=8.2 Hz, 1H), 6.81 (d, J=7.8 Hz, 1H), 4.54 (tt, J=12.0, 4.1 Hz, 1H), 4.38 (br s, 4H), 4.07 (s, 3H), 3.88 (t, J=4.8 Hz, 4H), 3.30 (d, J=12.4 Hz, 2H), 2.86 (dt, J=12.4, 2.3 Hz, 2H), 2.20 (dd, J=11.8, 2.2 Hz, 2H), 2.04 (dq, J=12.3, 4.1 Hz, 2H).
