Reaction Steps

To bromoacetophenone (322.8 mg, 1.62 mmole) and anhydrous K2CO3 (896 mg, 6.48 mmole) in ethanol (20 ml), 250 mg (1.62 mmole) 4-mercaptobenzoic acid was added and the mixture refluxed overnight. The solvent was evaporated and water added to the solid residue. The basic aqueous solution was extracted with ethyl acetate to remove unreacted bromoacetophenone. The aqueous layer was acidified to yield a precipitate which was filtered and dried (356 mg). m/z 271 (M−1)+. 1H NMR (DMSO) δ 4.75 (2H, s, —CH2-), 7.35-7.72 (5H, m, 5×ArH), 7.82 (2H, d, 2×ArH), 8.05 (2H, d, 2×ArH).
