Cyclohexylamine → N-cyclohexyladamantane-1-carboxamide

참여 물질

반응 단계

1-Adamantanecarboxylic acid (10.8 g, 0.06 mole) was dissolved in N,N-diethyl-1,1,2,3,3,3-hexafluoropropylamine (13.4 g, 0.06 mole) as described in example 1. After the reaction mixture cooled to room temperature, cyclohexylamine (14.88 g, 17.2 ml, 0.15 mole) was added slowly and a heavy precipitate of the amide appeared almost immediately. The N-cyclohexyl-1-adamantanecarboxamide was isolated as described in example 1 to give 14.8 g, 94.4%; mp 199.3-200.4° C. The analytical sample was recrystallized from cyclohexane and sublimed. Anal. Calcd. for C17H27NO: C, 78.18; H. 10.34; N, 5.36. Found: C, 77.97; H, 10.46; N, 5.32.
