Reaction Steps

To a solution of 3′-hydroxyacetophenone (19 g) in DMF (400 mL) was added K2CO3 (38.5 g) and the mixture was stirred for 3 hours at room temperature. 3,4-Dichlorobenzyl chloride (32.7 g) and potassium iodide (1.16 g) were added to the reaction mixture and stirred for 48 hours. After completion of the reaction, the mixture was poured into ice and water mixture and stirred for 15 minutes, solid was filtered and washed with water and hexanes. Solid was dissolved in DCM and precipitated by adding hexanes to get pure 1-[3-(3,4-dichloro-benzyloxy)-phenyl]-ethanone (30 g) 1H NMR (400 MHz, CDCl3) 7.53-7.60 (m, 3H), 7.46 (d, 1H), 7.39 (t, 1H), 7.25-7.30 (m, 1H), 7.14-7.19 (m, 1H), 5.07 (s, 2H), 2.60 (s, 3H).
