Reaction Steps

To a stirred solution of 11.6 g. (38 mmol) of 3,4-diphenylmethylenedioxybenzyl alcohol in ether (80 ml.) and pyridine (0.6 ml.) at 20° C. was added dropwise a solution of SOCl2 in ether (40 ml.). The mixture was cooled to 0°-5° C., and CH2Cl2 and water were added. The layers were separated, and the organic layer was washed with water and saturated aqueous NaCl, dried over MgSO4 and concentrated to dryness to yield 3,4-diphenylmethylenedioxybenzyl chloride (11.43 g.) as a colorless viscous oil: tlc (silica gel CH2Cl2 : Rf 0.8; ir (CCl4) no --OH--, nmr (CCl4) δ 4.34 (s, 2H), 6.74 (d,j=8) 2H, 6.67 (s, 1H), 7.1-7.6 (m, 10H). ##STR11##
