YieldReaction ConditionsOperation in experiment
81% General procedure: 3-Cyanobenzaldehyde (11a) or 4-cyanobenzaldehyde (11b) (15 mmol) and malonic acid (30 mmol) were dissolved in pyridine (30 mL). Piperidine (3.0 mmol) was added and the reaction was heated for 4 h at 100 C. The reaction was cooled to room temperature and 5 M HCl (25 mL) was added slowly. The resulting white precipitate was collected by filtration, washed with water and dried to give (E)-3-cyanocinnamic acid (12a) or (E)-4-cyanocinnamic acid (12b) in yields of 81% and 78%, respectively.

To a solution of methyl trans-3-cyanocinnamate (4.74 g, 25.3 mmol) in 100 mL of tetrahydrofuran and 50 mL of H2 O at room temperature was added lithium hydroxide monohydrate (2.65 g, 63.2 mmol). The resulting mixture was allowed to stir for 16 h. The tetrahydrofuran was removed in vacuo and the residue was diluted with saturated aqueous NaHCO3 and washed with hexane. The organic layer was discarded. The aqueous layer was acidified and extracted with ethyl acetate. The organics were washed with brine, dried over MgSO4 and concentrated in vacuo to afford 4.35 g (99%) of the title compound. 1 H NMR (CDCl3): δ 8.21 (s, 1H), 8.02 (d, 1H), 7.85 (d, 1H), 7.62 (t, 1H), 7.61 (d, 1H), 6.73 (d, 1H).

With hydrogenchloride; potassium carbonate;palladium; In water; To 200 ml of a solution of 20.0 g potassium carbonate in 250 ml water, 15 g of <strong>[16642-93-6]3-cyanocinnamic acid</strong> was added; the resulting mixture was heated until all the acid was in solution. The solution was cooled and filtered and rinsed with water to 250 ml total volume. Then 0.95 g of 10% palladium on carbon was added and the solution was hydrogenated at 8.5 psi for two hours. The reaction mixture was filtered, and then acidified to a pH of about 1 by the dropwise addition of concentrated hydrochloric acid, being careful to avoid too much foaming. The mixture was chilled in an ice bath and filtered to collect the precipitated product acid. The precipitate was rinsed several times with cold water and dried overnight, to give 13 g of the above-identified product as a solid, melting point 95 C.
