Reaction Steps

The above obtained crude 2,4-dibenzyloxybenzyl chloride [VII] was dissolved in dimethyl sulfoxide (150 ml) and then thereto was added sodium cyanide (4 g), followed by stirring for 2 hours at room temperature (20° C.). The reaction mixture was added to water (1 liter) and extracted with dichloromethane (1 liter). The dichloromethane extract was concentrated under reduced pressure and the residue was purified by a silica gel column [inner diameter: 10 cm, length 50 cm; developer: dichloromethane-hexane 1:1 (v/v) mixed solution] and furthermore, was recrystallized from diethyl ether-hexane 2:1 (v/v) mixed solution to obtain 2,4-dibenzyloxyphenylacetonitrile [VIII] (14.3 g, yield from [VI]: 70%). Melting point: 99°-100° C.
