実験手順
33.1 g (100 mmol) of 1-diphenylmethyl-3-methyl-3-methylsulphonyloxyazetidine are added to a suspension of sodium cyanide (11 g, 225 mmol) in dimethylformamide (90 ml) and the mixture is stirred at 65°-70° C. for 6 hours. It is cooled and poured onto a water/ice mixture, the product is filtered off, washed with water and dried at 50° C. and 21.75 g (83%) of 3-cyano-1-diphenylmethyl-3-methylazetidine, melting point 86°-88° C., are obtained.
