Acetic Acid → 3-[3-(6-Methoxy-m-tolyl)-1,2-benzisoxazol-5-yl]-6-(trifluoromethyl)-2,4(1H,3H)-pyrimidinedione

참여 물질

반응 단계

A mixture of 5-amino-3-(6-methoxy-m-tolyl)-1,2-benzisoxazole (8.40 g, 0.033 mol), 2-dimethylamino-4-(trifluoromethyl)-6H-1,3-oxazin-6-one (7.60 g, 0.036 mol), and acetic acid is refluxed for three hours, cooled, poured onto ice, and diluted with water. The resultant aqueous mixture is filtered to obtain a solid. The solid is washed with water and dried to give the title product as a pink solid which is identified by NMR spectral analyses.
