Procedure:
To a solution of methyl 4-[(diethoxyphosphoryl)methyl]benzoate (0.911 g, 3.18 mmol; see Preparation 4(i) above) in THF (10 mL, dry) under a nitrogen atmosphere was added sodium hydride (0.678 g, 60%, 18.8 mmol).

Procedure:
12-Hydroxydodecanoic acid (1 g) was dissolved in methylene chloride (25 ml), and triethylamine (2 ml) was added to the solution. To the mixture, while it was ice-cooled and stirred, was added dropwise 1-propanesulfonyl chloride (1.03 ml). After 1.5 hours of stirring, the reaction mixture was distributed into chloroform and water, and the chloroform layer was dried with anhydrous sodium sulfate and concentrated. The residue thus obtained was subjected to chromatography on a silica gel column with an eluent system of chloroform-hexane (2:1) to give 12-propanesulfonyloxydodecanoic acid (1.49 g). The product (210 mg) was dissolved in N,N-dimethylformamide (DMF). N-Hydroxysuccinimide (75 mg) and N,N'-dicyclohexylcarbodiimide (148 mg) were added, and the mixture was stirred for 12 hours. The precipitates obtained were removed by filtration and the filtrate was concentrated to give the active ester of 12-propanesulfonyloxydodecanoic acid. The active ester was dissolved in DMF, and 6-(4'-N-glycyl-spicaminylamino)purine hydrochloride (250 mg) and triethylamine (0.73 ml) were added. The mixture was stirred for 12 hours. The reaction mixture was concentrated, and the residue was subjected to chromatography on a silica gel column with an eluent system of chloroform-methanol (6:1) to give SPK230 in the yield of 480 mg.

Procedure:
4.8 cm3 of triethylamine were added with stirring, at a temperature in the region of 20° C. and under an inert atmosphere, to a solution of 5 g of methyl (3R,4R)-4-[3-oxo-3-(6-methoxyquinolin-4-yl)propyl]piperidine-3-acetate in 60 cm3 of dimethylformamide. After stirring for 15 minutes at this temperature, 1.5 cm3 of propargyl bromide were added over approximately 15 minutes and then, after 15 minutes, the mixture was heated at a temperature in the region of 45° C. for 4 hours. After cooling to approximately 20° C., the reaction mixture was poured onto approximately 700 cm3 of water and then the mixture was extracted with 4 times 80 cm3 of diethyl ether. The combined extracts were washed with 3 times 80 cm3 of water, dried, filtered, and concentrated under reduced pressure (5 kPa) at a temperature in the region of 40° C. The evaporation residue was purified by chromatography at atmospheric pressure on a column of silica gel (particle size 20-45 μm; diameter 4 cm; silica volume 500 cm3), elution was carried out with pure ethyl acetate, and 60-cm3 fractions were collected. Fractions 9 to 20 were combined and then concentrated as under the above conditions. 4.3 g of methyl (3R,4R)-4-[3-oxo-3-(6-methoxyquinolin-4-yl)propyl]-1-[prop-2-ynyl]piperidine-3-acetate were obtained in the form of an oil with a yellow color.

The solvent was evaporated under reduced pressure, and the obtained residue was dissolved in ethanol (4 mL). Concentrated hydrochloric acid (2 mL) was added, and the mixture was stirred at 80° C. for 4 hr. The reaction mixture was concentrated, aqueous potassium carbonate solution was added to the residue, and the precipitated crystals were collected by filtration. The crude crystals were purified by preparative HPLC to give the title compound (19 mg) as white crystals.

The reaction mixture was poured over a 10% HCl-ice mixture, then extracted three times with 250 ml ethyl acetate. The organic layer was washed five times with 200 ml water, dried and evaporated to dryness. The residue was purified on a silica column (200 g) eluting with hexane:ethyl acetate (9:1). Crystallization from acetone-hexane gave 1.52 g of N-n-butyl-3-(3,5-di-t-butyl-4-hydroxybenzoyl)pyrrole (mp 101°-103° C.).
