Versuchsvorschrift

Add the crude methiodide of 1-diethylamino-6-m-methoxyphenylhexan-3-one (2.5 g) in methanol (10 cc) ice-cold to a solution obtained by adding 2-methylcyclopentane-1,3-dione (0.5 g) to an ice-cold solution of sodium (0.21 g) in methanol (10 cc). Allow the reaction mixture to warm to room temperature and leave for 16 hours, after which add N hydrochloric acid (10 cc) and saturated brine (100 cc), and ether-extract the solution. Evaporate the washed and dried extracts to obtain the crude adduct 2-(6-m-methoxyphenyl-3-oxohexyl)-2-methylcyclopentane-1,3-dione as a gum.
