Reaction Steps

To a solution of 6-chloro-5-nitro-1H-isochromen-1-one (950 mg, 0.0042 mol) in methanol (30 mL, 0.7 mol) was added triethylamine (0.64 mL, 0.0046 mol) and (R)-2-aminopropanamide hydrochloride (0.58 g, 0.0046 mol). The reaction was heated to 55° C. overnight and the solvent was removed under reduced pressure. The residue was purified by flash chromatography to afford the product as light yellow solid.
