General procedure of the synthesis of 2-alkyl-2(N,N-dialkyl)aminoadamantanes (IIa–IId). To the Grignard reagent prepared from 0.025 mol of magnesium and 0.018 mol of an alkyl halide in 15–20 mL of tetrahydrofuran was added a solution of 0.009 mol of aminonitrile I in 10 mL of tetrahydrofuran. The mixture was heated at 40°C with stirring for 4 h, then cooled and mixed with 0.5 g of water. After separating
