Procedure:
A mixture of 6-(4-bromobutoxy)-indan-1-one prepared by the process described in step (1) above (100 gm, 0.282 mol, 80% purity) and sodium iodide (42 gm, 0.28 mol) in acetonitrile was refluxed for 30 minutes and then cooled to room temperature. 1-(2,3-dichlorophenyl)-piperazine hydrochloride (68 gm, 0.294 mol) and triethyl amine (77 gm, 0.761 mol) were added to the mixture and the resulting mixture was refluxed for 4-6 hr. After solvent was removed, the residue thus obtained was dissolved in chloroform, washed with water which treatment with chloroform and Hydrochloric acid gave 140 g of 6-[4-[4-(2,3-dichlorophenyl)-1-piperazinyl]butoxy]-indan-1-one hydrochloride. This on chloroform solution was basified with ammonium hydroxide to pH 9.5 and extracted with chloroform twice 2×500 ml. The combined chloroform layer was concentrated using rotavapour under reduced pressure to get a residue which on purification with methanol gave 85 gm of 6-[4-[4-(2,3-dichlorophenyl)-1-piperazinyl]-butoxy]-indan-1-one of the formula 2 which has identical characteristic of product obtained for the Example 1, step-2.

Ethyl acetate was added to the reaction mixture, which was washed with 2 N hydrochloric acid and then with a saturated aqueous sodium hydrogencarbonate solution. The organic layer was dried over anhydrous sodium sulfate and then concentrated under reduced pressure to obtain 2-acetyl-3-(3-cyanophenyl)-N-(3-phenyl-2-propene-1-yl) acrylamide.

Procedure:
To a 100-mL three-neck round bottom flask equipped with an overhead stirrer, thermocouple, and condenser with gas inlet for nitrogen, was charged with KOt-Bu (95%, 8.3 g, 70.40 mmol, 4.0 eq) and 2-methyltetrahydrofuran (36 mL) followed by morpholine (18.5 mL, 210.6 mmol, 12.0 eq). The mixture was heated to 90-95° C. and then a solution of (S)-1-(6-bromo-1-methyl-1H-pyrrolo[3,2-b]pyridin-5-yl)ethan-1-amine (4.46 g, 210.6 mmol) in 2-methyltetrahydrofuran (9 mL) was added dropwise via a syringe pump over a period of one hour. Following addition of the amine, the transfer vessel was rinsed with 2-methyltetrahydrofuran (5 mL). The rinse was added to the reaction mixture, which was stirred at reflux for one hour. HPLC analysis indicated the reaction was complete. The slurry was then cooled to 60° C. and water (15 mL) was added, which dissolved the solids. The organic and aqueous phases were separated at 40-50° C. The aqueous phase was extracted with 2-methyltetrahydrofuran (20 mL) at 50° C. The organic layers were combined and concentrated under reduced pressure to afford crude product (9.0 g) which contained residual morpholine. The crude product was heated in hot toluene (30 mL). Some undissolved solids remained and the hot solution was decanted into a clean receiver. The toluene solution was cooled, resulting in crystallization of solids. The solution was further cooled in a refrigerator at 2-8° C. for one hour. The solids were filtered, washed with toluene (10 mL), and dried to afford the title compound as a tan solid (2.85 g).
