Reaction Conditions

Reaction Steps

To a test tube (outside diameter 21 mm φ×overall length 160 mm), 100 mg of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-(phenylmethylidene)hydrazine ((40-b)-(15)-5), 0.5 ml of methanol, 10 mg of 10 wt % Pd-c and one drop of concentrated hydrochloric acid were added and the mixture was stirred at 0° C. for 7 hours under hydrogen atmosphere. An unsolved substance was removed by filtration and washed with methanol. The filtrates were combined and concentrated under reduced pressure to give 70 m g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-39)
