Procedure

Methanesulfonyl chloride (0.09 mL, 1.16 mmol) was added dropwise to a mixture of the above amine (107 mg, 0.220 mmol) and powdered K2CO3 (274 mg, 1.98 mmol) in CH2Cl2 (10 mL) at 0° C. The mixture was allowed to warm to room temperature and was stirred for 16.5 hrs. Water was added, the phases were separated, and the aqueous phase was extracted with CH2Cl2 (1×). The combined organic extracts were dried (Na2SO4) and the solvent removed under vacuum. Recrystallization from CH2Cl2/MeOH gave 5-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-3-[1-(methylsulfonyl)-4-piperidinyl]-7-(4-morpholinyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine (108 mg, 87%): mp 258-259° C.; 1H NMR (CDCl3) δ 7.81 (dd, J=8.4, 0.5 Hz, 1H), 7.41 (t, JHF=53.5 Hz, 1H), 7.39 (t, J=8.2 Hz, 1H), 6.84 (d, J=7.7 Hz, 1H), 4.93 (tt, J=10.5, 4.2 Hz, 1H), 4.79 (br s, 2H), 4.16 (br s, 2H), 4.07 (s, 3H), 4.01-3.90 (m, 6H), 3.14 (m, 2H), 2.89 (s, 3H), 2.60 (m, 2H), 2.35 (m, 2H); Anal.
