Reaction Steps
To 3-(4-chlorophenyl)-propionaldehyde (0.74 g, 4.39 mmol) was added zinc iodide (0.07 g, 0.22 mmol) and trimethylsilyl cyanide (0.522 g, 5.27 mmol) with caution (exothermic reaction). After stirring the mixture at room temperature for 20 min a solution of ammonia in methanol (7N, 4.4 ml, 31 mmol) was added and stirring was continued overnight. The solvent was evaporated and the residue was purified by chromatography (column: Isolute® Flash-NH2 from Separtis; eluent:heptane/ethyl acetate=2:1) to yield a light yellow liquid (0.43 g, 50%); MS (ISP): 195.3 ((M+H)+).
