Procedure
A mixture of 10.01 g (0.050 mol) of 8-fluoro-5-methoxy-1,2,4-triazolo[4,3-c]pyrimidine-3(2H)-thione in 8.6 g of methanol was prepared and cooled with an ice water bath. Sodium methoxide in methanol (32.4 g of 25 percent, 0.15 mol) was added under nitrogen with stirring and cooling. Afar 2.5 hours, 25.6 mL of ice cold 6.25N aqueous hydrochloric acid was added with stirring to the thick slurry obtained. The resulting mixture was diluted with a little water and the solids were recovered by vacuum filtration and dried under reduced pressure to obtain 8.26 g (83 percent of theory) of the title compound as a colorless powder. The compound melts at 155°-160° C. and then resolidifies and does not remelt up to 230° C.
