A round bottom flask was charged with 6-chloro-5-nitro-1H-isochromen-1-one (950 mg, 0.0042 mol), methanol (30 mL, 0.7 mol), triethylamine (0.64 mL, 0.0046 mol) and (R)-2-aminopropanamide hydrochloride (0.58 g, 0.0046 mol) and the reaction heated to 55° C. overnight. The reaction went to 90% completion. The solvent was removed and the residue purified by flash chromatography (40 g silica gel, 0-10% MeOH/DCM) to obtain the pure product as a light yellow solid. MS m/z=296.4 (M+H).
