34% | Example 1; A. 3-Methyl-isonicotinonitrile.; To 3-methyl-pyridine 1 -oxide (15.90 g, 150 mmol) is added at 0 0C during 30 min. dimethylsulfate (15.60 mL). The resulting reaction mixture is stirred overnight at 40 0C. A solution of KCN (10.75 g, 165 mmol) in a mixture of EtOH/water 1 : 1 (120 mL) is added and the reaction mixture is stirred overnight at 40 0C. The reaction mixture is concentrated in vacuo and the residue is partitioned between EtOAc and water. The aqueous phase is extracted with EtOAc and the combined organic layers are dried over Na2SO4, filtered and concentrated at reduced pressure. Purification by flash column chromatography (silica gel, cyclohexane / EtOAc 85 : 15) affords the title compound as orange crystals (6.00 g, 50.80 mmol, 34%). 1H NMR (400 MHz, DMSO-(Z6) delta ppm 8.76 (s, 1 H), 8.64 (d, J = 4.9 Hz, 1 H), 7.80 (d, J = 4.9 Hz, 1 H). | |

The resulting reaction mixture is stirred overnight at 40 0C. A solution of KCN (10.75 g, 165 mmol) in a mixture of EtOH / water 1 : 1 (120 mL) is added and the reaction mixture is stirred overnight at 40 0C. The reaction mixture is concentrated in vacuo and the residue is partitioned between EtOAc and water. The aqueous phase is extracted with EtOAc and the combined organic layers are dried over Na2SO4, filtered and concentrated at reduced pressure. Purification by FCC (silica gel, cyclohexane / EtOAc 85 : 15) affords the title compound as orange crystals (6.0 g, 50.8 mmol, 34%). 1H NMR (400 MHz, DMSO-d6, 298 K): delta = 8.76 (s, 1 H), 8.64 (d, J = 4.9 Hz, 1 H), 7.80 (d, J = 4.9 Hz, 1 H). | |
A. A mixture of 3-methyl-pyridine 1-oxide (20 g, 0.183 mol) and iodoethane (32 mL, 0.403 mmol) is stirred 16 h. 200 mL water is added, the aqueous layer is separated and washed with Et2O. The collected aqueous layer is warmed to 50 C. and a solution of KCN (24 g, 0.366 mol) in 60 mL of water is added slowly in one hour. After an additional one hour stirring, the mixture is extracted with Et2O. The combined solvent is dried and concentrated to dryness. The residue is purified by silica gel column chromatography with hexanes:EtOAc=4:1 as eluent to provide 3-methyl-isonicotinonitrile. |

In N,N-dimethyl-formamide; for 120h; | B. To a solution of <strong>[7584-05-6]3-methyl-isonicotinonitrile</strong> (12.25 g, 0.104 mmol) in 100 mL of DMF is added dimethylformamide dimethyl acetal (22 mL, 0.166 mol) portionwise in 5 days. The solvent is evaporated to dryness. The residue is purified by silica gel column chromatography with hexanes:EtOAc=4:1 as eluent to provide 3-(2-dimethylamino-vinyl)-isonicotinonitrile. |
