Procedure
A mixture of (R)-2-(5-amino-1-oxoisoquinolin-2(1H)-yl)-2-phenylacetamide (120 mg, 0.00041 mol), N,N-dimethylformamide (1.5 mL, 0.019 mol), N,N-diisopropylethylamine (0.1 mL, 0.0008 mol), N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.3 g, 0.0008 mol) and (S)-2-(4-chlorophenyl)propanoic acid (0.091 g, 0.00049 mol) was allowed to stir over night at room temperature. The solvent was removed and the residue purified by flash chromatography (12 g silica gel, 0-10% MeOH/DCM) and again by preparative HPLC (reverse phase) to obtain the product as an off white solid. MS m/z=460.3 (M+H). 1H NMR (400 MHz; DMSO-d6) δ 9.95 (s, 1H), 8.13-8.11 (d, J=7.99 Hz, 1H), 8.02 (s, 1H), 7.74-7.72 (d, J=7.60 Hz, 1H), 7.71-7.69 (d, J=8.03 Hz, 1H), 7.55 (s, 1H), 7.50-7.32 (m, 10H), 6.99-6.97 (dd, J=7.89&1.86 Hz, 1H), 6.74 (s, 1H), 6.39-6.37 (d, J=8.02 Hz, 1H), 4.00-3.94 (q, J=6.97 Hz, 1H), 1.44-1.41 (d, J=7.11 Hz, 3H).
