Procedure:
Diethylamine (153 g) is added to a solution, maintained at 20° C., of (R)-2-chloropropionyl chloride (87.7 g) in chloroform (600 cc), in the course of 1 hour. The reaction mixture is washed with distilled water (500 cc), with an aqueous 1N hydrochloric acid solution (3×500 cc) and then with distilled water (500 cc). The organic phase is dried over sodium sulphate, filtered and then concentrated to dryness under reduced pressure (2.7 kPa) at a temperature in the vicinity of 30° C. The residue obtained is distilled under reduced pressure (17 Pa).

Procedure:
To one-half mole of sodium benzenesulfinate in water in a 2 liter beaker is introduced 49 g (0.5 mole) of concentrated sulfuric acid. To the resulting suspension of benzenesulfinic acid is then added 101 g (0.5 mole) of diisopropyl azodicarboxylate. The mixture is stirred and heated to 60° C. (30 minutes). The yellow color of the azo ester gradually disappears. The oily product is extracted with benzene and separated from the lower aqueous layer. Removal of the benzene by evaporation leaves a clear oil which crystallizes when introduced into an 80/20 hexane/benzene mixture. The filtered crystals are dried at 60° C.

Procedure:
Under argon, 3-benzyl-6-(2-iodobenzyl)-1,4-dimethylpiperazine-2,5-dione (polar isomer from 1.5, 100 mg, 0.22 mmol) was stirred together with diisopropylamide (0.5 ml), trimethylsilylacetylene (40 mg, 0.4 mmol), Pd(PPh3)4 (60 mg, 0.05 mmol) and CuI (10 mg, 0.05 mmol) in DMF (abs., 5 ml) at 80° C. for 12 h. After cooling and addition of H2O, the mixture was extracted with methyl tert-butyl ether and the organic phases were dried and concentrated. Purification by column chromatography gave 21 mg (23%) of the target compound as a colorless oil.

Procedure:
To 4 ml of a DMF solution containing 111 mg of [2-(5-fluoro-8-methoxychroman-6-yl)-2-[4-(5-trifluoromethyl-[1,2,4]oxadiazol-3-yl)phenylimino]-1-methylsulfanylethylidene]carbamic acid methyl ester (Example (189a)), 37 mg of 4-hydrazinothiazole-5-carboxylic acid ethyl ester (Example (185c)) and 0.031 ml of triethylamine were added. The resulting mixture was stirred at 85° C. for 20 hours under a nitrogen atmosphere. The reaction mixture was concentrated. The residue was dissolved in 4 ml of methanol and 0.032 ml of acetic acid, and then 83 mg of sodium cyanotrihydroborate was added thereto. The mixture was stirred at room temperature for 15 hours, and then 100 ml of ethyl acetate and 50 ml of water were added thereto. The organic layer was washed with 50 ml of water and then with 50 ml of saturated brine and was dried over anhydrous magnesium sulfate. The desiccating agent was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by NAM silica gel column chromatography (methanol-ethyl acetate) to give the title compound (74 mg).
