To a stirred solution of methyl 5-bromo-3-(ethylamino)-2-methylbenzoate (600 mg, 2.2 mmol) and 4-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl]morpholine (1.0 g, 3.3 mmol) in dioxane (5 mL), aqueous 2M Na2CO3 solution (3.96 mL, 7.93 mmol) was added and solution was purged with argon for 15 min. Then Pd(PPh3)4 (255 mg, 0.22 mmol) was added and argon was purged again for 15 min. Reaction mass was heated at 100° C. for 4 h. On completion, reaction mixture was diluted with water and extracted with 10% MeOH/DCM (3 times). Combined organic layer was dried over sodium sulphate. Removal of the solvent under reduced pressure followed by column chromatographic purification afforded the desired compound (800 mg, 98%).
