Procedure
A round bottom flask was charged with 5-nitro-isochromen-1-one (2.5 g, 0.013 mol), methanol (40 mL, 1 mol), triethylamine (4 mL, 0.03 mol) and methyl 2-amino-2-(4-chlorophenyl)acetate hydrochloride (4.0 g, 0.017 mol) and the reaction heated at 50° C. for 4 hours. The solvent was removed and the residue purified by flash chromatography (40 g silica gel, 0-10% MOH/DCM) to yield the product as a yellow solid. MS m/z=373.3 (M+H).
