53% | Stage #1: With 2,2,6,6-tetramethyl-piperidine In tetrahydrofuran at -78 - 25℃; for 0.5 h; Stage #2: With hexachloroethane In tetrahydrofuran at -78℃; for 0.5 h; |
To a stirred solution of 2,2,6,6-tetramethyl piperidine (17.16 mL, 100.854 mmol) in THF (100 mL) was added n-BuLi (2.17 M, 44.26 mL, 96.052 mmol) at -30°C. After stirring the mixture for 15 mm at 25°C, it was cooled to -78°C and 4-cyanopyridine (5 g, 48.026 mmol) in THF (40 mL) was added dropwise. After stirring the reaction mixture for 30 mm at -78°C, hexachioroethane (23.87 g, 100.854 mmol) in THF (50 mL) was added at -78°C. The resulting mixture was stirred for 30 mm at -78°C and was quenched with saturated NH4C1 solution. Water (100 mL) was added to the reaction mixture and extracted with ethyl acetate (4 x 300 mL). The combined organic layer was dried over anhydrous sodium sulfate, concentrated under reduced pressure to afford the crude material which was purified by column chromatography using silica (100-200 mesh) and 5percent EtOAc-hexane as eluent to afford 3-chloropyridine-4-carbonitrile (3.5 g, 25.26 1 mmol, 53percent) as pale white solid.

44.8% | With hydrogenchloride; sodium hydroxide; phosphorus pentachloride; trichlorophosphate In n-heptane; water | Preparation 71 3-Chloro-isonicotinonitrile The title compound was prepared by a modified procedure based on the method of J. Rokach and Y. Girard, J. Heterocycl. Chem. 1978, 15, 683-684. 4-Cyanopyridine-N-oxide (250 g, 2.08 mol) was added portionwise to a stirred suspension of PCl5 (599.94 g, 2.88 mol) and POCl3 (800 mL, 8.71 mol) at 20° C. under nitrogen, in a reactor fitted with a reflux condenser. During the addition the temperature rose to 41° C. The mixture was stirred at 100° C. for 3 h then cooled to 95° C. and transferred to a mixture of 6M HCl (200 mL) and a 6:4 mixture of ice and water (5994 g) at such a rate that the temperature stayed below 15° C. (about 35 min). The resulting brown solution was cooled to below 5° C. and taken to pH 4.15 by adding 33percent aqueous NaOH (about 4.5 L), keeping the temperature below 5° C. The resulting beige precipitate was filtered and washed thoroughly with water (4*500 mL), sucking as dry as possible. The residue was suspended in water (1.5 L) and n-heptane (7 L) and stirred at 30° C. for 1 h. The aqueous phase was separated and extracted further with n-heptane (2*2 L), stirring for 30 min each time at 30° C. The combined heptane layers were combined, dried (Na2SO4, 136 g), filtered and the resulting solution was concentrated under reduced pressure to a weight of 1.9 kg (about 3 L), at which point the product began to crystallise. The mixture was cooled to 0° C., stirred for 1.5 h then the product was filtered, washed with cold n-heptane (2*125 mL) and dried at room temperature in a circulating air drier to give the product (129.08 g, 44.8percent) as a crystalline solid; m.p. 73.4° C. |
39.9% | Stage #1: at 105℃; Stage #2: at 0℃; |
Step A: Preparation of 3-chloroisonicotinonitrile: In a 4 neck 3L round bottom flask equipped with mechanical stirrer and condenser, was added 4-cyanopyridine-n- oxide (50 g, 416 mmol), phosphoryl trichloride (153 ml, 1665 mmol), and phosphorous pentachloride(121 g, 583 mmol). The reaction was stirred at 105 0C overnight. The reaction mixture was cooled and then slowly added in portions to 2 kg ice. The pH was adjusted to about 8 by slow addition of 50percent NaOH. The mixture was extracted with ethyl acetate. The organic layer was dried and concentrated. The residue was purified by silica gel chromatography, eluting with 5-10percent ethyl acetate to give the desired product (23 g, 39.9percent yield) as light yellow solid. |
