The solution of 2-benzyloxy-6-bromomethyl-naphthalen (18) (1 equi.), and triphenylphosphine (1.1 equi.) in DMF (0.6 mL/mmole was stirred at 95 C for 15 h, cooled to room temperature, and quenched with ethyl acetate. The resulting white solid of (6-benzyloxynaphthalen-2-ylmethyl)-triphenylphosphonium bromide (19) was filtered and washed with ethyl acetate. Yield 98%.
