A 250 mL round bottom flask was charged with 5-nitro-isochromen-1-one (40 g, 0.2 mol), (2R)-2-Aminopropan-1-ol (18 g, 0.24 mol), triethylamine (100 mL, 0.7 mol) and methanol (500 mL, 10 mol) and the reaction heated at 88° C. for 1.5 hours. The product precipitated out upon cooling the reaction and was filtered to afford the product as a yellow solid. (17.3 g, 40% yield).
