Procedure

560 g (8.5 mol) of butan-2-one and 234 g (1.4 mol) of (1,2,2-trimethyl-bicyclo[3.1.0]hex-3-yl)ethanal were added to 48 g (0.75 mol) of potassium hydroxide dissolved in 500 ml of water and 1.4 1 of methanol. The reaction mixture was stirred overnight with ice-bath cooling, poured into 3 l of water and extracted with diethyl ether. The extract was washed with water, dried (MgSO4) and evaporated in vacuo. The residue was distilled at 108° C./0.1 Torr to give 140 g (45% yield) of 3-methyl-5-(1,2,2-trimethylbicyclo[3.1.0]hex-3-yl)pent-3-en-2-one.
