Procedure

Dissolve 5g. of 5-(triphenylmethyl)-2-cyanopyridine in a mixture consisting of 50 ml. of water and 1.0 liter of methanol. Add 4 g. of potassium hydroxide and heat the mixture at reflux for 15 hours. Remove the methanol under reduced pressure, triturate the residue with water and dry the solids obtained thereby. Crystallize the product from acetonitrile to obtain the product of this example. m.p. 239°-240° C.
