Procedure

To a solution of methyl 5-bromo-3-(ethyl((trans)-4-((2-methoxyethyl)(methyl)amino)cyclohexyl)amino)-2-methylbenzoate (30 g, 68.02 mmol), 4-(prop-2-yn-1-yl) morpholine (25.51 g, 204 mmol) and triethylamine (20.61 g, 204 mmol) in DMF (300 mL) was bubbled Argon for 20 min. Then CuI (3.87 g, 20.36 mmol) and Pd (PPh3)4 (7.85 g, 6.79 mmol) were added and Argon was bubbled through for further 20 min. The reaction mixture was heated at 105° C. for 4 h and then cooled to room temperature. The reaction was quenched with water (100 mL) and the aqueous phase was extracted with 10% MeOH/DCM (400 mL×3). The combined organic extracts were dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel column chromatography to afford the title compound (21 g, 63.7% yield).
