Abstract
An improved process for the preparation of p-hydroxybenzyl cyanide by the reaction of p-hydroxybenzyl alcohol with an alkali metal cyanide, by carrying out the process in the presence of an alkyl formate, especially n-propyl formate. The cyanide product is a valuable intermediate for the preparation of the .beta.-adrenergic blocking agent atenolol.
