実験手順

To a solution of 5-nitro-isochromen-1-one (1.5 g, 0.0078 mol) in methanol (20 mL, 0.4 mol) was added triethylamine (2 mL, 0.02 mol) and (S)-2-aminopropanamide hydrobromide (1.6 g, 0.0094 mol) and the resulting mixture was heated at 50° C. overnight. The reaction mixture was cooled to room temperature wherein the product precipitated out. The precipitate was filtered and dried to yield the pure product as a yellow solid. MS m/z=262.2 (M+H).
