A solution of 4.37 g. of 1,3-diacetyl-2-[4-isopropenyl-3-pyridyl]-5-(3-methyl-2-octyl)resorcinol in 50 ml. of toluene was placed in a high pressure bomb with 40 ml. of liquid ammonia. The mixture was shaken at room temperature overnight. The excess ammonia was allowed to escape; the residue was triturated with water and extracted with chloroform. The chloroform extracts were washed twice with water, dried over anhydrous sodium sulfate, and evaporated in vacuo. The residue was recrystallized from ether-petroleum ether (30°-60°) to yield the pure product; m.p. 128°-129°.
