cf. CA 59, 9969g. The reaction between tolylhydrazine (I) and cyanomethyl esters of carboxylic acids (in mole ratio 2:1) gave the following MeC6H4NHNHCOR (II) [R, m.p., and % yield (based on cyanomethyl ester) being given for the reactions conducted in AcOEt and without solvent resp.]: p-II: BZNHCH2, 176-7¡ã, 95, 98.5; PhSO2NHCH2, 178-80¡ã, 95, 97; p-MeC6H4SO2NHCH2, 163-4¡ã, 97, 100; 4-pyridyl (as HCl salt), 239-41¡ã (decomposition), 73, 87; m-II: BZNHCH2, 178-9¡ã, 92, 98; PhSO2NHCH2, 145-6¡ã, 95, 95; p-MeC6H4SO2– NHCH2, 158-9¡ã, 90, 94; 4-pyridyl, 161-2¡ã, 69, 81; o-II: Bz-NHCH2, 172-3¡ã, 80, 89; PhSO2NHCH2, 145-6¡ã, 81, 85; p-MeC6H4SO2NHCH2, 164-5¡ã, 62, 79; 4-pyridyl, 209-10¡ã, 50, 85. The reaction mixture was usually kept 20 hrs. at room temperature In cases where no solid separated, either inoculation or distillation of the solvent in vacuo followed by addition of Et2O initiated the crystallization
