Add catalyst Pd(OAc)2 (120 mg) and 1,3- bis(diphenylphosphino)propane (360 mg) to the mixture and then heat at 13O0C in a pressure vessel with stirring for 20 hours. Cool the reaction mixture to room temperature and remove the insoluble EPO <DP n="50"/>material by filtration. Wash the solid with MeOH (25 mL) and then add 5.0 mL of 6.0 N aqueous HCl to the filtrate. Stir the mixture at room temperature for 20 hours. Concentrate the reaction mixture under vacuum, dilute it with EtOAc (100 mL), wash the organic layer with aq. Na2CO3 (2 x 50 mL) and dry (MgSO4). Filter the dried extract and concentrate under vacuum to afford crude product as pink oil. Purify the crude product by column chromatography to afford pure product as colorless oil.

55.2% To a solution of <strong>[38186-84-4]2-chloro-5-fluoro-3-methylpyridine</strong> D38 (0.50 g, 2.82 mmol) in dry toluene (12.5 ml) were added sodium t-butoxyde (0.462 g, 4.81 mmol), Pd2(dba)3 (0.315 g, 0.344 mmol), BINAP (0.642 g, 1.031 mmol) and benzophenone imine (0.692 ml, 4.12 mmol). The resulting mixture was degassed (3.x.pump/N2) and then heated to 80° C. After 1 h stirring, the mixture was cooled down to room temperature, diluted with Et2O (400 ml) and filtered through a celite pad. Volatiles were evaporated, the resulting oil was dissolved in THF (34 ml) and HCl (1.408 ml of a 2 M aqueous solution, 2.82 mmol) was added. The mixture was stirred at room temperature for 1.5 h, then neutralized with a saturated NaHCO3 aqueous solution and diluted with DCM (200 ml). The inorganic layer was back-extracted with DCM (2.x.50 ml). The collected organic layers were dried (Na2SO4), filtered and evaporated. The residue was purified by flash chromatography on silica gel (Biotage SP4 12M, Cy/EtOAc 60/40). Collected fractions gave the title compound D39 (0.20 g, 1.554 mmol, 55.2percent yield from D38, two steps), as an orange solid. MS: (ES/+) m/z: 127 (M+1). C6H7FN2 requires 126.1H NMR (400 MHz, DMSO-d6) delta(ppm): 7.73 (d, 1H), 7.23 (dd, 1H), 5.60 (bs, 2H), 2.04 (s, 3H).

The residue was purified by flash chromatography on silica gel (Biotage SP4 12M column, Cy/EtOAc 60/40). Collected fractions gave the title compound DIl (0.20 g) as an orange solid. MS: (ES/+) m/z: 127 (M+l). C6H7FN2 requires 126. 1H NMR (400 MHz, DMSO-J6) delta ppm: 7.73 (d, 1 H), 7.23 (dd, 1 H), 5.60 (bs, 2 H), 2.04 (s, 3 H).
