실험 절차

To 25 ml of ethanol were added 4-(2-bromoacetyl)benzoic acid (486 mg, 2 mmole) and N-methyl thiourea (180 mg, 2 mmole). The reaction mixture was refluxed for 3 hr and the TLC showed the disappearing of the starting materials and the formation of a fluorescent product. The reaction was cooled on ice. The product was collected on filtration and washed with ethanol pre-cooled to 0° C. twice (2×3 ml), followed by diethyl ether. After drying, 486 mg product was obtained. 1H NMR (DMSO-d6, 400 MHz) δ 7.97 (2H, d), 7.89 (2H, d), 7.32 (1H, s), 2.96 (3H, s).
