実験手順
71.2 g of 2-cyclopropyl-4,6-bis-trichloromethyl-1,3,5-triazine are dissolved in 70 ml of tetrahydrofuran, and at room temperature are added, with stirring, 300 ml of a concentrated aqueous ammonia solution. The reaction mixture is stirred for 30 minutes; it is then diluted with water, and the formed emulsion is extracted with ether. The ether phases are collected, dried, filtered and subsequently concentrated by evaporation. The residue crystallises and there remain 48 g of the crystalline title product, m.p. 111°-114° C.
