Procedure:
Pyrrolidine (271 μL, 5.50 mmol) was added to a solution of azetidine-1,3-dicarboxylic acid mono-tert-butyl ester (1.0 g, 4.97 mmol), HATU (2.09 g, 5.50 mmol) and DIPEA (2.18 mL, 12.52 mmol) in DMF (100 mL) and the resulting mixture stirred at ambient temperature for 1 h, then concentrated in vacuo. The resulting oil was partitioned between EtOAc and water. The organic layer was separated, washed with water and brine, then dried (MgSO4) and concentrated in vacuo to give 3-(pyrrolidine-1-carbonyl)azetidine-1-carboxylic acid tert-butyl ester as a colourless oil. TFA (3 mL) was added to a solution of 3-(pyrrolidine-1-carbonyl)-azetidine-1-carboxylic acid tert-butyl ester in DCM (15 mL) and the mixture stirred at ambient temperature for 1 h, then loaded onto an Isolute® SCX-2 cartridge (25 g). The cartridge was then washed with methanol and the desired product was subsequently eluted using 2 M NH3 in MeOH. The product was collected and concentrated in vacuo to afford the title compound as a colourless oil (550 mg, 72%). 1H NMR (CD3OD, 400 MHz) δ 3.93-3.65 (m, 5 H); 3.43-3.28 (m, 4 H) and 2.00-1.81 (m, 4 H).

Procedure:
To a solution of the compound prepared in Example 180 (5.9 g) in N,N-dimethylformamide (hereinafter abbreviated to DMF) (120 mL) were added benzyl bromide (4.3 mL) and potassium carbonate (9.9 g) and the reaction mixture was stirred at room temperature for 12 hours. The reaction mixture was filtered through Celite (trade name) and concentrated in vacuum condition to remove DMF. To the obtained residue was added water and the organic layer was extracted with ethyl acetate. The obtained organic layer was dried over magnesium sulfate and concentrated in vacuum condition. The obtained residue was purified by column chromatography on silica gel (hexane:ethyl acetate=6:1→4:1) to give the title compound (6.1 g) having the following physical data.

Procedure:
1.65 G. of sodium in 60 ml. of absolute ethanol are treated dropwise with 11.4 g. of dibenzo[b,e]thiepin-11(6H)-one-oxime in 60 ml. of absolute ethanol. The mixture is stirred at 50° C. for 3 hours and then cooled to 5°-10° C. The mixture is then treated dropwise with 15.3 g. of 3-diethylamino-propyl chloride, stirred at 50° C. for 16 hours and subsequently evaporated under reduced pressure. The residue is dissolved in chloroform, washed with water, dried over sodium sulfate and evaporated under reduced pressure. The resulting residue is purified by chromatography over aluminum oxide using chloroform for the elution. A by-product is first eluted and there is subsequently eluted the desired N,N-diethyl-N'-{dibenzo[b,e]thiepin-11(6H)-ylidene}-1,3-propanediamine-N'-oxide which is used directly in the process described in the first paragraph of this Example.

A suspension of ethyl [1-[1-(2-fluorophenetyl)piperidin-4-yl]-2-oxoindolin-6-yl]acetate (32.5 g, 76.559 mmol) in phosphoryl chloride (75.0 ml) was refluxed under heating for 2.5 hours (after 30 min., the suspension was dissolved). After removing the solvent, ethyl acetate (100 ml) and a 2N aqueous sodium hydroxide solution were added thereto, to separate the organic layer. It was washed with a 2N aqueous sodium hydroxide solution, water and brine, and then added with anhydrous magnesium sulfate and activated clay. After filtering, the solvent was removed, to give the title compound (yield: 33.2 g, 74.952 mmol, 97.9%).
