• 中文摘要： Reaction of 6-amino-5-cyano-3-methyl-1,4-diphenyl-1H,4H-pyrano(2,3-c) pyrazole 1 with triethyl orthoformate in acetic anhydride gave its methanimidate, which reacts with primary aliphatic and aromatic amines to give 4,6-dihydro-3-methyl-1,4-diphenyl- 6-(alkyl)pyrazolo(4',3':5,6)pyrano(2,3-d)pyrimidine-5(1H)-imine and the starting compound 1, respectively. Treatment of 1 with 0-aminophenol gave 5-(2-benzoxalyl)-1,4-dihydro-3-methyl-1,4-diphenylpyrano(2,3-c)pyrazol-6-amine.
