YieldReaction ConditionsOperation in experiment
In tetrahydrofuran; at 20℃; for 18.0h; INTERMEDIATE 36tert-Butyl 6-chloropyridine-2-carbo6-Chloropyridine-2-carboxylic acid (5.00 g, 31.7 mmol) was dissolved in DCM (150 mL) and oxalyl chloride (5.45 mL, 63.5 mmol) and DMF (1 mL) were added. The reaction mixture was stirred for 3 h, concentrated in vacuo and azeotroped with DCM. The residue was dissolved in THF (150 mL) and potassium ieri-butoxide (3.39 mg, 47.6 mmol) was added. The reaction mixture was stirred for 18 h, quenched with water (250 mL) and extracted with DCM (3 x 150 mL). The combined organic fractions were washed with sat aq NaHC03 (150 mL), dried (MgS04) and concentrated in vacuo. The residue was purified by column chromatography to give the title compound (3.11 g, 46%) as a white solid. LCMS (ES+): 236.1 [MNa]+.

YieldReaction ConditionsOperation in experiment
96% With pyridine; p-toluenesulfonyl chloride; at 20℃; tert-Butyl 6-chloropyridine-2-carboxylate 6-Chloropicolinic acid (80.0 g, 0.51 mol) was dissolved in pyridine (300 ml) and tert-butanol (1.60 l), then p-toluenesulphonyl chloride (194 g, 1.02 mol) was added in portions. The reaction mixture was stirred at room temperature overnight. After addition of saturated aqueous sodium hydrogencarbonate solution, the mixture was stirred at room temperature for 1 h. The reaction mixture was concentrated to a volume of 1.50 l and diluted with heptane (500 ml), ethyl acetate (500 ml) and water (500 ml). The organic phase was removed, washed with saturated aqueous sodium chloride solution, dried over magnesium sulphate and filtered, and the filtrate was concentrated. 104 g (96% of theory) of the title compound were obtained. 1H-NMR (400 MHz, CDCl3) delta [ppm]=1.61 (s, 9H), 7.45-7.48 (dd, 1H), 7.74-7.77 (t, 1H), 7.93-7.95 (dd, 1H).
