Методика

To a suspension of 5.0 g of 5-(methylthio)-8-[3-(trifluoromethyl)phenyl]-3H,6H-1,4,5a,8a-tetraazaacenaphthylen-3-one in 35 ml of acetic acid is added 2.64 g of isopropylamine. The reaction mixture is heated on a steambath for 18 hours. The resulting solution is cooled to room temperature and 17 ml of ethanol added. The mixture is cooled to 10° C. and 35 ml of ethanol and 20 g of ice added. The mixture is stirred for an additional 30 minutes at -10° C.
