Example 4Coupling of the Acyl Imidazole Derivative of Meptazinol with 4-Aminobenzoic Acid 0.1 g of the acyl imidazole derivative of meptazinol and 1.2 eq 4-aminobenzoic acid (hydrochloride salt) were suspended in 10 vol of THF, TFA (2 eq) was added and the mixture was heated at 35 to 40° C. for 22 hours. This provided meptazinol PABA carbamate with 90.4% conversion as determined by HPLC.
