実験手順: A solution of methyl 2,6-dichloroisonicotinate (4.8 g, 23.3 mmol) and N-propylmethanesulfonamide (3.8 g, 28.0 mmol) in dioxane (190 mL) was degassed with argon. Potassium phosphate tribasic (6.9 g, 32.6 mmol), xantphos (810 mg, 1.40 mmol) and Pd2 dba3 (427 mg, 0.47 mmol) were added, and the reaction mixture was stirred at 100° C., sealed, for 16 h. The reaction mixture was filtered on cellite, concentrated in vacuo, and purified by flash chromatography (2×300 g silica gel, 0 to 35% EtOAc in hexane) to give methyl 2-chloro-6-[(methylsulfonyl)(propyl)amino]isonicotinate. 1H NMR (400 MHz, CD3OD) δ 7.87 (s, 1H), 7.72 (s, 1H), 3.97 (s, 3H), 3.91 (t, J=7.2 Hz, 2H), 3.14 (s, 3H), 1.68-1.52 (m, 2H), 0.94 (t, J=7.4 Hz, 3H). sealed, for 16 h The reaction mixture was filtered on cellite concentrated in vacuo purified by flash chromatography (2×300 g silica gel, 0 to 35% EtOAc in hexane)
