Procedure:
23 g of crude 5-bromo-5-(4-chlorophenoxy)-3,3-dimethylpent-1-en-4-one, dissolved in 30 ml of acetonitrile, were added dropwise to a solution of 28.6 g (0.42 mol) of imidazole in 250 ml of acetonitrile, in the course of 5 minutes. The mixture was then heated to the boil for a further 3 hours and the solution was concentrated under reduced pressure. The oily residue was taken up in 200 ml of ethyl acetate and the mixture was washed with three times 50 ml of water. After the organic phase had been dried over anhydrous sodium sulphate, it was concentrated by evaporation, the residue was taken up in 200 ml of acetone and a filtered solution of 20.2 g (0.07 mol) of naphthalene-1,5-disulphonic acid in 100 ml of acetone was added. The precipitated salt was filtered off under suction, 100 ml of water and 100 ml of dichloromethane were added to it, and the mixture was then rendered alkaline with 10% strength sodium carbonate solution. The organic phase was separated off and concentrated. The oily residue crystallized on trituration with ether/petroleum ether. 7.4 g (34.7% of theory) of 5-(4-chlorophenoxy)-3,3-dimethyl-5-(imidazol-1-yl)-pent-1-en-4-one of melting point 72° to 74° C. were obtained.

Procedure:
A solution of 3-acetyl-4-chromanone (1.8 g, 9.5 mmoles, described in Example 5) in dry tetrahydrofuran (20 ml) is added dropwise to a suspension of 57% sodium hydride (1.17 g, 28.5 mmoles) in tetrahydrofuran (30 ml) and the mixture is heated at reflux temperature for 15 min. A solution of diethyl oxalate (1.39 g, 9.5 mmoles) is added dropwise under an atmosphere of nitrogen. The reaction mixture is heated at reflux temperature overnight and cooled to -40° C. A solution of 50% aqueous acetic acid (4 ml) is added and the reaction mixture evaporated. The residue is partitioned between chloroform and water, the organic phase is separated and the aqueous phase is re-extracted with chloroform. The combined chloroform extracts are dried and evaporated. The residue is subjected to chromatography on silica gel. Elution with chloroform affords 4-(4-chromanon-3-yl)-2,4-dioxobutyric acid ethyl ester (VII; R1, R2, R3R4 and R17 = H, R19 = C2H5 and X = O), which is crystallized from ether, m.p. 117°-119° C.

Procedure:
A solution of 3-phenylpyrrolidine (294 mg, 2 mmol) in dry dichloromethane (6 mL) is cooled in an ice bath, and butanoyl chloride (266 mg, 2.5 mmol, 1.25 eq) and triethylamine (417 μL, 3 mmol, 1.5 eq) are added. After stirring for 6 hours at room temperature the reaction mixture is diluted with dichloromethane (10 mL). The organic solution is subsequently washed with 1 M KHSO4, 5% NaHCO3 and brine. After drying over Na2SO4, dichloromethane is removed in vacuo and the crude material is purified by flash chromatography (silicagel, ethyl acetate/toluene 1:4). The fractions containing 1-(3-phenylpyrrolidin-1-yl)butan-1-one are collected and the solvent is removed in vacuo to give 378 mg of colorless oil.
