Reaction Steps

To 100 mg (0.3466 mmole) (±)-(2-chlorophenyl)-(6,7-dihydro-4H-thieno[3,2-c]pyrid-5-yl) acetonitrile was dissolved in 2 mL t-butanol and add 1.5 mL HCl was added. The reaction mixture was refluxed for 9 hrs at 100° C. In the end, after the completion of reaction, water was added and pH was brought to 4 with 10% KOH solution. The product was extracted with 5 mL dichloromethane and proceeded as given in the earlier example. The yield was 40 mg (38%).
