The reduction of nitrile XXI to amine was described in [9]; the hydrogenation of amine XIX has not been described in the literature. Ill [7], amine XX was obtained by hydrogenation of nitrile XXI over Raney Ni (100 atm., 60~ We carried out the transformation of amine XIX into cyclohexylamine XX under milder conditions (15 atm, 20~ and with complete conversion (according to GLC data). The refractive index of the amine~ obtained (nD 2~ 1.4646 was ...
