Reaction Steps

To a mixture of (S)-2-bromo-N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)nicotinamide (52) (150 mg, 0.31 mmol) in anhydrous 1,4-dioxane (3 mL) in a sealed tube, morpholine (1 mL, excess amount) was added and the resulting mixture was stirred at 140° C. for 6 h. The mixture was allowed to cool to RT and then partitioned between ethyl acetate and water. The organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by ISCO column chromatography (silica gel cartridge, 0-10% MeOH-DCM) followed by prep-TLC plate purification (10% MeOH-DCM) to afford the product (S)—N-(1-(8-chloro-1-oxo-2-phenyl-1,2-dihydroisoquinolin-3-yl)ethyl)-2-morpholinonicotinamide (compound 53). ESI-MS m/z: 489.0 [M+H]+.
