Procedure
The suspension of 1,2,3,4-tetrahydro-2-naphthoic acid (500 mg, 2.84 mmol) in 5 ml of toluene was treated with oxalyl chloride (720 mg, 5.675 mmol). The mixture was stirred at 50° C. for 5 hrs. All volatile materials were removed in vacuo and product 1,2,3,4-Tetrahydro-2-naphthoyl chloride was obtained as a colorless oil, which was used for next step reaction without further purification.
