YieldReaction ConditionsOperation in experiment
90% Add -trifluoromethyl-pyridine^-carboxylic acid methyl ester (80.0 g, 390 mmol) to a mixture of THF (240 mL) and tert-butylmethyl ether (400 mL). Add the solution slowly to a 3 M methylmagnesium chloride in THF (390 mL, 1.17 moles) and maintain 8 0C to 16 0C. Cool the mixture to 0 0C and add a mixture of 5 M hydrochloric acid (257 mL, 1.29 moles) and water (200 mL). Separate the phases and concentrate the organic phase under reduced pressure. Add heptane (160 mL) and cool the mixture to 5 0C. Collect the precipitate by vacuum filtration and rinse the solid with heptane (20 mL) followed by pentane (30 mL). Vacuum dry the solid to afford the title compound as a tan solid (72.3 g, 352 mmol, 90 %). 1H NMR (400 MHz, DMSO d6) delta 8.04 (t, J= 7.7 Hz, IH), 7.94 (d, J= 7.9 Hz, IH), 7.69 (d, J= 7.0 Hz, IH), 5.40 (s, IH), 1.43 (s, 6H).

YieldReaction ConditionsOperation in experiment
With hydrogenchloride; In water; at 80℃; for 48h; General procedure: Example 3, step 1: Preparation of 6-chloro-pyridine-2-carboxylic acid methyl ester (10). To a solution of 6-chloro-pyridine-2-carboxylic acid (48 g, 0.31 mol) in methanol (770 ml) was added concentrated HC1 (6 ml). The mixture was stirred at 80C for 48 hours then concentrated to remove the volatile. The crude product was diluted with ethyl acetated and washed with Sat. NaHCC"3 solution. The organic layer was dried with anhydrous Na2S04 and concentrated to give -chloro-pyridine-2-carboxylic acid methyl ester as a white solid. LC-MS: m/z 172.0 (M+H)+.
