Reaction Steps

Thionyl chloride (10.4 g, 87.7 mmol) was added dropwise to a 0° C. solution of 4-ethoxybenzyl alcohol (11.0 g, 72.4 mmol) in dry CH2Cl2 (150 mL) with a catalytic amount of DMF (1 mL). Upon addition, reaction was allowed to stir for 5-10 minutes, while monitoring through TLC (CH2Cl2) for completion. Reaction mixture was concentrated under reduced pressure and the residue dissolved in minimal THF and then precipitated in cold H2O to yield a white precipitate. The solid was collected, taken up in CH2Cl2, dried and concentrated. The resulting oil was solidified by cooling with CO2/acetone. The compound as a white solid, which decomposes upon melting 11.3 g(92%).
