Procedure: 3-Ethyl-6-fluoro-2(3H)-benzothiazolon-5-yl isocyanate (1.16 g) and ethyl pipecolic acid (1.07 g) were dissolved in toluene (5 ml). A catalytic amount of triethylamine was added thereto, and the resultant mixture was stirred at 25° C. for 12 hours. Water was added to the reaction mixture, which was then extracted with toluene. The extract was dried and concentrated to give 2-[3-ethyl-6-fluoro-2(3H)-benzothiazolon-5-yl]tetrahydroimidazo[1,5-a]-pyridine-1,3(2H,5H)-dione (0.89 g). m.p., 162°-164° C. was then extracted with toluene The extract was dried concentrated
