YieldReaction ConditionsOperation in experiment
Example 1c 4-Cyano-2-methyl-benzoic acid ethyl ester Compound of example 1b (32 g; 178 mmol) was treated with conc. HCl (64 ml) and water (320 ml), cooled to 0 C., then treated to a dropwise addition of an aqueous solution of NaNO2 (12.33 g; 178 mmol, 320 ml) over a period of 1 h at 0-5 C. The diazonium salt solution was neutralized with Na2CO3 and added slowly to an aqueous solution of KCN and CuCN (13.38 g; 204.4 mmol, 19.34 g; 204.4 mmol, 500 ml), maintained at 0-5 C., with vigorous stirring over a period of 1 h. The reaction mixture was stirred for 30 min. at 0-5 C. and left stirring overnight at room temperature. It was subsequently heated on steam bath for 30 min., treated with an aqueous 10% FeCl3 solution and extracted with EtOAc (3*500 ml). The organic layer was washed with water, brine, dried (Na2SO4), concentrated, purified using flash chromatography (silica gel, 5% EtOAc-PE 60-80 C.) and crystallized using EtOAc-PE 60-80 C. to obtain the title compound as a pure white solid. Yield, 20 g (59.2%); mp, 64-65 C.; MS (EI): 189 (M+), 144 (100%), 116, 89; analysis: C11H11NO2, 0.5H2O requires C, 66.70; H, 6.06; N, 7.07; found: C, 67.11; H, 5.88; N, 6.88%.
