Reaction Steps

To a stirred solution of methyl 5-bromo-3-(ethyl-(tetrahydro-2H-pyran-4-yl)amino)-2-methylbenzoate (1 g, 2.82 mmol) and 4-((morpholino)methyl)phenylboronic acid pinacol ester (1.03 g, 3.38 mmol) in dioxane/water mixture (10 mL+2 mL), Na2CO3 (1.08 g, 10.14 mmol) was added and solution purged with argon for 15 min. Then Pd(PPh3)4 (0.325 g, 0.28 mmol) was added and argon was purged again for 10 min. Reaction mass was heated at 100° C. for 2 h. On completion, reaction mixture was diluted with water and extracted with 10% MeOH/DCM. Combined organic layers were dried over Na2SO4 and solvent removed under reduced pressure to afford crude material which was purified by column chromatography over silica gel to afford the title compound (0.75 g, 59%).
