5-Chloropyridine-2-carboxylic acid methyl ester

To a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 mL) was added Pd(OAc)Intermediate 1 : methyl δ-chloro^-pyridinecarboxylate To a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 ml.) was added Pd(OAc)Intermediate 1 : methyl δ-chloro^-pyridinecarboxylate To a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 ml.) was added Pd(OAc)Intermediate 1 : methyl δ-chloro^-pyridinecarboxylate To a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 ml.) was added Pd(OAc)Intermediate 1 : methyl δ-chloro^-pyridinecarboxylateTo a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 ml.) was added Pd(OAc)I. methyl 5-chloro-2-pyridinecarboxylate To a solution of 2-bromo-5-chloropyridine (30.0 g, 155.9 mmol) in MeOH (280 mL) was added Pd(OAc)5-chloro-2(chloromethyl)pyridine; [00372] To a 0 C solution of 5-chloropicolinic acid (3.00 g, 19.0 mmol) indichloromethane (20 mL) was added sulfurous dichloride (2.78 mL, 38.1 mmol), after which the reaction was warmed to room temperature and stirred at that temperature for 4 hours. The reaction was then concentrated to dryness, then reconstituted in dichloromethane (5 mL). Methanol (10 mL) was added to the reaction mixture, and the reaction was allowed to stir at room temperature for 12 hours, after which it was then diluted with water, extracted with ethyl acetate (3 x 50 mL), washed with water, then washed with saturated sodium bicarbonate solution, dried (magnesium sulfate), filtered and concentrated. Purification was achieved by silica gel chromatography (ISCO 80g) using 0 to 80% ethyl acetate in hexanes to afford
