Alkylation of methyl p-hydroxyphenylcarbamate with allyl bromide and 1,4-dibromobutane leads to formation of the corresponding methyl p-alkoxyphenylcarbamates. Reactions of methyl p-allyloxyphenylcarbamate with benzaldehyde, p-methoxybenzaldehyde, p-nitrobenzaldehyde, and p-chlorobenzaldehyde oximes in boiling ethanol in the presence of N-chlorobenzenesulfonamide sodium salt yields 3-aryl-5- (p-methoxycarbonylaminophenoxymethyl)-4,5-dihydroisoxazoles...
