Sodium Cyanide → HCID 13873006, compound

Participants

Reaction Steps

That is, 2,4-dihydroxybenzaldehyde [IV] is benzylated with benzyl chloride to produce 2,4-dibenzyloxybenzaldehyde [V], then [V] is reduced with sodium borohydride to produce 2,4-dibenzyloxybenzyl alcohol [VI] and then, [VI] is chlorinated with thionyl chloride to produce 2,4-dibenzyloxybenzyl chloride [VII]. Then, [VII] is allowed to react with sodium cyanide to obtain 2,4-dibenzyloxyphenyl acetonitrile [VIII], thereafter [VIII] is hydrolyzed with an alkali to produce 2,4-dibenzyloxyphenylacetic acid [IX], then this [IX] is chlorinated with thionyl chloride to produce 2,4-dibenzyloxyphenylacetyl chloride [X] and further, this [X] is allowed to react with L-asparagine or glutamine p-nitrophenyl ester to obtain [IIa].
