Reaction Conditions

Temperature	45 °C

Reaction Steps

A round bottom flask was charged with (R)-2-(5-amino-6-methyl-1-oxoisoquinolin-2(1H)-yl)propyl acetate (175 mg, 0.000638 mol), 2-(3-fluoro-4-(trifluoromethyl)phenyl)acetic acid (210 mg, 0.00096 mol), N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (610 mg, 0.0016 mol), N,N-diisopropylethylamine (0.28 mL, 0.0016 mol) and N,N-dimethylformamide (8 mL, 0.1 mol). The reaction mixture was stirred at 45° C. for 24 hours. The reaction was quenched with water and extracted with ethyl acetate, washed with sodium bicarbonate, brine, and dried. The solvent was removed under reduced pressure and the residue was purified by flash chromatography to afford the product as a light yellow oil.
