Reaction Steps

2-Aminothiazole (I31) (1.0 equiv., 5.00 mmol, 0.500 g) and 2-formylbenzoic acid (I32) (1.2 equiv., 6.00 mmol, 0.900 g) were mixed in ethanol (8 ml) and heated at reflux for 2 h. Upon cooling, a precipitate was formed. The product was isolated by filtration and washed with isopropyl ether to afford 3-(2-thiazolylamino)-isobenzofuran-1(3H)-one (I33) (0.944 g, yield=81%).
