Conditions

Temperature
52 °C

Procedure

A round bottom flask was charged with 5-nitro-isochromen-1-one (2 g, 0.01 mol), methanol (40 mL, 1 mol), (R)-2-aminopropanamide hydrochloride (2.0 g, 0.016 mol) and triethylamine (2.6 mL, 0.019 mol) and stirred at 52° C. for 3 hours. The product (yellow solid) precipitated out which was filtered and carried on to the next reaction without any further purification. MS m/z=262.3 (M+H).
