Procedure

To a stirred solution of ethyl 4-hydroxybenzoate (530 g, 3.19 mol) in DMF (6 L) were added K2CO3 powder (1102 g, 7.97 mol, 2.5 eq.), NaI (1195 g, 7.97 mol, 2.5 eq.) and PMB-Cl (599.4 g, 3.83 mol, 1.2 eq.) at ambient temperature. The reaction mixture was heated at 50° C. overnight under nitrogen atmosphere. The reaction mixture was cooled to ambient temperature and ice-water (9 L) was added to the reaction mixture. The resulting solid was filtered and washed with water (5 L), dried at 40° C. under vacuum to obtain product.
