A round bottom flask was charged with 2-(4-chloro-3-(trifluoromethyl)phenyl)acetic acid (170 mg, 0.00072 mol), N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (400 mg, 0.001 mol), N,N-diisopropylethylamine (0.2 mL, 0.001 mol), N,N-dimethylformamide (2 mL, 0.03 mol) and 2-(5-amino-1-oxoisoquinolin-2(1H)-yl)acetamide (120 mg, 0.00055 mol). The reaction was stirred for 16 h at room temperature and the solvent was removed and the residue purified by preparative HPLC (reverse phase) to yield the product as a white powder. MS m/z=437.8 (M+1). 1H NMR (400 MHz; DMSO-d6) δ 10.09 (s, 1H), 8.04 (d, J=8.07 Hz, 1H), 7.89 (bs, 1H), 7.83 (d, J=8.07 Hz, 1H), 7.73-7.70 (m, 2H), 7.63 (bs, 1H), 7.46 (t, J=8.0 Hz, 1H), 7.42 (d, J=7.76 Hz, 1H) 7.19 (bs, 1H), 6.64 (d, J=7.70 Hz, 1H), 4.56 (s, 2H), 3.92 (s, 2H).
