1-Adamantanecarboxylic acid (10.8 g, 0.06 mole) was added to N,N-diethyl-1,1,2,3,3,3-hexafluoropropylamine (13.4 g, 0.06 mole) contained in a wide mouth polyethylene bottle with magnetic stirring. The acid dissolved immediately during which time a highly exothermic reaction occurred. The reaction mixture was allowed to cool to room temperature and cold aqueous ammonia (250 ml) was added slowly. A heavy precipitate of the amide appeared almost immediately. After the addition was complete, the reaction mixture was stirred for about fifteen minutes. The 1-adamantanecarboxamide was collected and washed copiously with water followed by ethyl ether and dried. Yield: 10.7 g, 100%; mp 189.4-190.2° C. (Lit. mp 189° C., Stetter, et. al., Chem. Ber., 1960, 226-230). The analytical sample was recrystallized from cyclohexane and sublimed. Anal. Calcd. for C11H17NO: C, 73.76; H, 9.49; N, 7.82. Found: C, 73.67; H. 9.60; N, 7.78.
