Procedure

To a stirring mixture of the sulfonamide from Example 2 (175 mg, 0.76 mmol) and the phenylcarbamate of 4,6-dimethoxy-2-aminopyrimidine (210 mg, 0.76 mmol) in 3 ml of acetonitrile was added diazobicycloundecane (116 mg, 0.76 mmol). The solution was stirred for approximately 10 minutes. Acidification of the reaction mixture and filtration of the resulting solids afforded 300 mg of the desired compound m.p. 189°-192° C. NMR (200 MHz, CDCl3) 1.0 (m, 2H), 1.1 (m, 2H), 2.4 (m, 1H), 4.0 (s, 6H), 4.35 (s, 1H), 5.80 (s, 1H), 7.4 (br. s, 1H), 8.05 (s, 1H), 12.9 (s, 1H).
