This invention relates to a method for the novel preparation of 1-adamantanecarboxamides and 1-adamantaneacetamides. Adamantanecarboxamides and adamantaneacetamides are prepared in high yields (80-100%) by treating adamantanecarboxylic acid and adamantaneacetic acid with N,N-diethyl-1,1,2,3,3,3-hexafluoropropylamine, followed by addition of aqueous ammonia or the appropriate amine. The procedure, carried out at ambient temperature using common laboratory equipment, is both convenient and rapid, requiring no more than one or two hours. Several reactions can be carried out simultaneously.
