The following cyanohydrins XC6H4CH(OH)CN (I) were prepared by treating 1.25 moles aldehyde and 1 mole KCN with 1 mole H2SO4 (as a 1:1 solution) at 10-20° (X, m.p. or b.p., and % yield given): H, b12-14 98-102°, 73.4; p-NO2, 197°, 45.0; o-NO2, 213-15°, 41.6; m-NO2, b12 183-7°, 36.4; p-Cl, 198-9°, 66.3; o-Cl, b18-20 165-70°, 62.1; o-OH, 148°, 69.9. The following Et α-hydroxyarylacetates XC6H4CH(OH)CO2Et (II) were prepared by heating 0.015 mole I with 3 ml. absolute EtOH and 3 ml. concentrated H2SO4 (X, m.p. or b.p., and % yield given): H, b12 60-4°, 73.7; p-NO2, 55-6°, 43.3; o-NO2, 134°, 35.2; m-NO2, 38.5°, 27.3; p-Cl, 172-4°, 71.6; o-Cl, b12 88-91°, 81.3; o-OH, 212-14°, 76.4. When 0.03 mole II was heated 4 hrs. with 10 ml. absolute EtOH and 6 ml. 50% H2NNH2.H2O, the product distilled in vacuo and the solid was recrystallized from EtOH, the following XC6H4CH(OH)CONHNH2 were prepared X, m.p., and % yield given): H, 91-2°, 75.9; p-NO2, 223-5°, 53.7; o-NO2, 239°, 37.4; m-NO2, 156-7°, 76.2; p-Cl, 90-2°, 54.05; o-Cl, 174-5°, 71.7; o-OH, 260-2°, 54.3. The hydrazides had no inhibitory effect, even at high concentration, on tubercular bacilli.
