Procedure:
To a suspension of NMP (20 ml), acetone (20 ml) and potassium carbonate (8.85 g) was added 5-fluoro-2-nitro phenol (5.0 g, 30 mmol) in one portion. After 15 minutes, the suspension began to turn yellow. After stirring 30 minutes under nitrogen, 4-bromobutene (4.25 ml) was added and the suspension was refluxed for 18 hours. The suspension was poured into water and extracted with 3×200 ml of diethyl ether. The aqueous layer was acidified with 2N HCl and extracted with ether. The ether layers were combined, washed with 2N HCl and water and dried over anhydrous magnesium sulfate. Filtration and in vacuo concentration yielded 6.0 g of 2-(3-butenyloxy-4-fluoronitrobenzene, as an oil, which was used in the next step without further purification.

Procedure:
A mixture of 3-(1-hydroxyethyl)phenol (7 g), 2-chloromethylquinoline (9 g), potassium carbonate (7 g) and potassium iodide (0.3 g) in acetone (75 ml) was refluxed overnight. The reaction mixture was poured into water, and then thoroughly extracted with ethyl acetate (3×30 ml). The organic extract was washed with NaOH solution (1N), water, brine, and then dried over MgSO4. All volatiles were removed to obtain a dark brown liquid, which was chromatographed on silica gel (12% ethyl acetate in hexanes) to leave the desired product as a light yellow liquid.

Procedure:
The cyclisation is effected by dropwise addition of a solution of sodium t-amylate in toluene to the aforementioned phosphonium salt in suspension in the same solvent heated under reflux. After each addition, the yellow colouring of the phosphorane appears and then disappears almost immediately. After filtration of the sodium bromide, the toluene is evaporated and the 3-methyl chrom-3-ene is separated from the triphenyl phosphine oxide by a treatment with pentane.

Procedure:
4-Chlorophenylacetic acid (1.7 g, 10 mmol) and oxalyl chloride (2 ml, 23 mmol) were stirred in 100 ml methylene chloride with two drops of dimethylformamide for two hours. The solvent and excess oxalyl chloride were removed under vacuum to give p-chlorophenylacetyl chloride. The 4-chlorophenylacetyl chloride and 4,4,6,6-tetramethyl-1,3,5-cyclohexanetrione (1.5 g, 8.2 mmol) were dissolved in methylene chloride. Triethylamine (3 ml) was added and the resulting solution stirred at room temperature for 30 minutes. The solution was washed with 1 normal hydrochloric acid (1N HCl), 5% potassium carbonate (5% K2CO3) and saturated sodium chloride (brine), dried over anhydrous magnesium sulfate (MgSO4) and concentrated under vacuum. The residue was dissolved in 15 ml acetonitrile. Triethylamine (3 ml) and acetone cyanohydrin (0.3 g) were added and the mixture stirred at room temperature for 4 hours. Afer dilution with ether, the solution was washed with 1N HCl and extracted with 5% K2CO3. The basic extract was acidified with hydrochloric acid and extracted with ether. The ether extract was washed with brine, dried (MgSO4) and concentrated under vacuum yielding 1.0 g of an oil that solidified on standing (m.p. 57°-61° C). It was identified as such by nuclear magnetic resonance spectroscopy, infrared spectroscopy and mass spectroscopy.
