2,4-diphenyl- and 2-p-methylphenyl-4-phenyl-Δ2-oxazolin-5-ones react at 80-110 deg C with nitrosobenzene to give benzamidines.However, reactions conducted at room temperature afford in high yield, the heretofore undescribed Δ4-oxadiazolin-3-carboxylic acids by regiospecific 1,3-dipolar cycloaddition.Thermal decomposition of the oxadiazolinecarboxylic acids gives the corresponding benzamidines.
