Procedure:
Finally, phenacyl 3-benzyloxy-2-n-tetradecyl-octadecanoate (V) (1.81 g, 2.57 millimole) was dissolved in a mixed solvent (70 ml) of tetrahydrofuran and methanol (1:1) and 1N sodium hydroxide (7.70 ml, 7.70 millimole) was added thereto, and the mixture was reacted at 65° C. for 2.5 hours. The solvent was distilled off from the reaction mixture, and water and tetrahydrofuran were added to dissolve the residue. Then the solution was acidified with 2N hydrochloric acid (to pH of about 2) with ice cooling, and extracted with ethyl acetate, and the organic phase was washed with water and dried over anhydrous sodium sulfate. The solvent was distilled off from the organic phase, the residue was dissolved in a developing solvent (n-hexane:ethyl acetate=8:2), and the obtained solution was purified over a silicagel column (n-hexane:ethyl acetate=8:2). The fast eluting fractions comprising impurities were discarded and the later colorless fractions were pooled. The solvent was evaporated off from the pooled fractions, and the residue was purified over a silicagel column (benzene:ethyl acetate=9:1) again, to give 3-benzyloxy-2-n-tetradecyl-octadecanoic acid (VI) (878 mg, yield 58%) in the form of colorless oil.

Procedure:
1.0 Gram (2.7 mmol) of the 4,4,5,8-tetramethyl-6-(1,3-dimethyl-5-hydroxypyrazol-4-yl)carbonylthiochroman-1,1-dioxide obtained in Preparation Example 6 was dissolved in 10 ml of tetrahydrofuran, and further, 0.27 g (3.5 mmol) of pyridine and 90 mg of potassium iodide were added. Then, 0.63 g (3.5 mmol) of ethyl 2-bromopropionate was added, and the mixture was refluxed under heat for 7 hours. The reaction mixture was cooled to room temperature, and the solvent was distilled off under reduced pressure. The resultant residue was extracted by adding ethyl acetate, and the extract was consecutively washed with 10% hydrochloric acid, with a saturated sodium bicarbonate aqueous solution and with a saturated sodium chloride aqueous solution, and the solvent was distilled off under reduced pressure to give 0.57 g (yield 45%) of 4,4,5,8-tetramethyl-6-(1,3-dimethyl-5-(1-ethoxycarbonyl)ethoxypyrazol-4-yl)carbonylthiochroman-1,1-dioxide (Compound No. 40).

Procedure:
A mixture of 2-aminopyridine (12.5 g), 1,3-dichloro-2-propanone (17.7 g) and acetonitrile (100 ml) was heated under reflux for 2 hours and concentrated. An aqueous saturated solution of sodium bicarbonate was added to the residue and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The residue was subjected to silica gel chromatography to obtain crystals from an ethyl acetate-hexane hexane (3:2, v/v)-eluted fraction. Recrystallization from ethyl acetate-hexane gave 2-chloromethylimidazo[1,2-a]pyridine (7.52 g, yield 34%) as pale-yellow crystals. m.p. 93-94° C.

Procedure:
A 650 mg portion of potassium carbonate and 339 mg of 4-fluorobenzonitrile were added to a mixture of 1.0 g of tert-butyl [(1R)-1-(1-naphthyl)ethyl]{[(3R,4S)-4-phenylpyrrolidin-3-yl]methyl}carbamate and 10 ml of DMSO and stirred overnight at 110° C.
