Procedure

To an ice cold stirred solution of α-methyl-4-chlorobenzyl cyanide* (50g., 0.3 mole) in 500 ml. of pyridine containing a suspension of paraformaldehyde (36g., 1.2 mole) is added 1 ml. of benzyl triethylammonium hydroxide. The mixture is stirred under nitrogen at room temperature for 72 hours. The reaction mixture is poured into water and extracted with ether. The combined ether extracts are washed with water, saturated sodium chloride solution and dried over magnesium sulfate. The solvent is evaporated to give a thick oil, 58.4g, which is identified by nmr.
