Reaction Steps

To a solution of allyl 4-(4-cyanophenyl)-2-methyl-6-oxo-1-[3-(trifluoromethyl)phenyl]-1,4,5,6-tetrahydro-3-pyridinecarboxylate (Example 46) (1.00 g, 2.27 mmol) and tetrakis(triphenylphosphin)-palladium(0) (68 mg, 0.059 mmol) in tetrahydrofuran (50 ml) is slowly added morpholine (3.36 g, 38.6 mmol). After stirring at room temperature for 1 h, the reaction mixture is quenched with water (50 ml). The basic solution (pH ca. 10) is neutralised with 1 N hydrochloric acid, and the aqueous phase is extracted with ethyl acetate (2×100 ml). The combined organic layers are washed with water, dried, and the solvent is removed in vacuo to yield pure product.
