Yield:-
Reaction Conditions:
aluminum nickel in tetrahydrofuran;
Steps:
1 Process variant (a) STR116
154.2 g (0.814 mol) of 4,4-dimethyl-1-pyridin-3-yl-1-penten-3-one were dissolved in 750 ml of tetrahydrofuran and the solution was stirred with about 20 g of Raney nickel. The solution was filtered, a further 20 g of Raney nickel were added and hydrogenation was carried out under the usual pressure and at room temperature until, according to the thin layer chromatogram, no further starting material was present. The Raney nickel was filtered off from the solution, the filtrate was concentrated and the residue was distilled. 119.8 g (78% of theory) Of 4,4-dimethyl-1-pyridin-3-yl-pentan-3-one of boiling point 123°-130° C./2.3 mm Hg were obtained. STR118
