실험 절차

The general methods described in Example 101 were used with the following modifications. To one-third of the crude solution of 4-[3-(5,6-dimethyl-8-propyl-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridin-7-yl)propane-1-sulfonyl]benzoyl chloride in dichloromethane, described in Part B of Example 101, was added N-methyl butylamine (0.583 mL, 4.92 mmol) in lieu of morpholine, and the reaction was stirred overnight. Additional N-methyl butylamine (0.5 mL) was added, and the reaction was stirred for two hours. The crude product was recrystallized from ethyl acetate:hexane, and the crystals were dried for three hours in a vacuum oven at 90° C. N-Butyl-4-[3-(5,6-dimethyl-8-propyl-7H-imidazo[4,5-c]tetrazolo[1,5-a]pyridin-7-yl)propane-1-sulfonyl]N-methyl benzamide (770 mg, 1.46 mmol) was treated as described in Part C of Example 101. The crude product was recrystallized from ethyl acetate:hexane with a couple drops of methanol to provide crystals, which were isolated by filtration, washed with hexane, and dried for four hours under high vacuum at 50° C. to provide 0.56 g of 4-[3-(4-amino-6,7-dimethyl-2-propyl-1H-imidazo[4,5-c]pyridin-1-yl)propane-1-sulfonyl]-N-butyl-N-methylbenzamide as a white powder, mp 127.0–129.0° C. 1H NMR (300 MHz, CDCl3) δ 7.95 (d, J=8.4, 2H), 7.58 (d, J=8.4, 2H), 4.92 (br s, 2H), 4.42 (dd, J=7.8, 7.8, 2H), 3.55 (dd, J=7.8, 7.8, 1H), 3.21–3.05 (m, 4.5H), 2.90 (s, 1.5H), 2.77 (dd, J=7.7, 7.7, 2H), 2.43 (s, 3H), 2.39 (s, 3H), 2.23 (quint, J=7.6, 2H), 1.93–1.36 (m, 5H), 1.15 (quart, J=7.5, 1H), 1.07 (t, J=7.4, 3H), 0.99 (t, J=7.0, 1.5H), 0.81 (t, J=7.4, 1.5H);
