The reaction of guanidine carbonate with various ortho-fluorobenzaldehydes in N,N-diinethylacetamide was investigated as a potential route for preparing 2-aminoquinazolines. Eleven new 2-aminoquinazolines were elaborated in this manner in low to moderate yields. In general the best results were obtained with ortho-fluorobenzaldehydes possessing an electron withdrawing substituent at the other ortho
研究了碳酸胍与各种邻氟苯甲醛在N,N-二乙基乙酰胺中的反应,作为制备2-氨基喹唑啉的潜在途径。用这种方法以低到中等的产率制备了十一种新的2-氨基喹唑啉。通常,用在另一个邻位上具有吸电子取代基的邻氟苯甲醛可获得最好的结果。使用未拆分的2-氟苯甲醛,2,5-二氟苯甲醛和2-氟-5-甲氧基苯甲醛获得复杂的混合物。
