Reaction Steps

A solution of methyl 2,6-dichloroisonicotinate (1 g, 4.85 mmol), isopropyl amine (0.286 g, 4.85 mmol), Cs2CO3 (2.06 g, 6.3 mmol) in toluene (30 mL) was purged with argon for 10 min. Then, Pd(OAc)2 (0.108 g, 0.485 mmol) and BINAP (0.3 g, 0.485 mmol) were added and argon was purged again for 15 min. Reaction mass was stirred at 80° C. for 6 h. On completion, reaction mass was filtered and residue washed thoroughly with ethyl acetate. Combined filtrates were concentrated and purified by column over silica gel to obtain pure methyl 2-chloro-6-(isopropylamino)isonicotinate (0.3 g, 27.27%).
