The other compounds of Example 3 were prepared by essentially the same procedure using the corresponding carboxamide and acyl hydrazide. Acetonitrile was used as solvent in the preparation of 3-2. Compound [3-19] was isolated as a byproduct in the synthesis of 3-18. The methyl amides were prepared from their corresponding methyl esters and [METHYLAMINE] using well established protocols. The other amides were conveniently prepared from commercially available carboxylic acids and amines using 1- (dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride as the reagent and published procedures. Preparation of the acyl hydrazides was described in Procedures 3A, 3B, 3C and 3D. |
