실험 절차

Methanesulfonyl chloride (0.08 mL, 1.03 mmol) was added dropwise to a mixture of the above amine (102 mg, 0.211 mmol) and powdered K2CO3 (263 mg, 1.90 mmol) in CH2Cl2 (10 mL) at 0° C. The mixture was allowed to warm to room temperature and was stirred for 5 hrs. Water was added, the phases were separated, and the aqueous phase was extracted with CH2Cl2. The combined organic extracts were dried (Na2SO4) and the solvent was removed under vacuum. Recrystallization from CH2Cl2/MeOH gave 2-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-9-[1-(methylsulfonyl)-4-piperidinyl]-6-(4-morpholinyl)-9H-purine (105 mg, 88%): mp 236-239° C.; 1H NMR (CDCl3) δ 7.84 (s, 1H), 7.76 (dd, J=8.4, 0.5 Hz, 1H), 7.42 (t, JHF=53.6 Hz, 1H), 7.36 (t, J=8.2 Hz, 1H), 6.81 (d, J=7.8 Hz, 1H), 4.57 (tt, J=11.7, 4.4 Hz, 1H), 4.38 (br s, 4H), 4.09 (m, 2H), 4.06 (s, 3H), 3.88 (t, J=4.8 Hz, 4H), 2.96 (dt, J=12.5, 2.8 Hz, 2H), 2.88 (s, 3H), 2.35-2.20 (m, 4H); Anal. Calcd. for C24H28F2N8O4S: C, 51.2; H, 5.0; N, 19.9. Found: C, 51.0; H, 4.9; N, 19.7%.
