Abstract
Reaction of 4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carboxyl chloride with anesthesin followed by hydrolysis of the formed ester has afforded 4-[4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-carbonylamino]benzoic acid. The acid chloride has been used for acylation of various amines to yield the corresponding diamides. Reaction of [4-(4-methoxyphenyl)tetrahydro-2H-pyran-4-yl]methylamine with chlorides of N-substituted p-aminobenzoic acids has led to formation of diamides.
