2-methylcyclopropane-1-carbohydrazide

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 8.0 gm (0.07 mole) of 2-methylcyclopropanecarboxylic acid hydrazide, 9.46 gm (0.07 mole) of ethyl-3-pyridyl ketone, 10 drops of glacial acetic acid and 100 ml of EtOH was refluxed 20 hr. Tlc (9:1 Skellysolve B/Ethyl acetate on silica gel) shows no remaining starting material. The reaction mixture was cooled to room temperature and evaporated in vacuo to give a liquid. The liquid solidified on standing. The solid was slurried in ether, collected and dried to give 4.77 gm (29%) of the title compound having a melting point of 137.3° C. was refluxed 20 hr evaporated in vacuo to give a liquid collected dried
