실험 절차

A flask was charged with 1.54 g. (0.01 mole) of 7-amino[1,2,5]thiadiazolo[3,4-d]pyrimidine prepared by the process set forth in Example 1 and 4.0 g. (0.025 mole) of 2-chloro-6-fluorobenzylamine prepared by the process set forth in Example 2. The suspension was stirred and heated at 105° C. for 18 hours. Ten ml. water and 20 ml. hexane were added in one portion and the resulting solid collected by filtration. The cake was washed with hexane and dried at 50° C. in vacuo to afford 2.86 g. (97%) of product. M.p. 224°-226° C.; tlc on silica gel in chloroform-methanol (8:1) showed a single fluorescent blue spot at Rf =0.8; NMR (DMSO-d6) δ 4.92 (2H, s); 7.21 (broad s, 3H); 8.44 (s, 1H); 9.45 (s, 1H).
