Procedure
2-Chloro-6-methylbenzenesulfonyl chloride (8, 7.82 g, 34.8 mmol) was added to a solution of 7 (8.83 g, 31.6 mmol) in pyridine (7.67 ml, 95.0 mmol) and the reaction mixture was stirred at room temperature overnight. CH2Cl2 and H2O were added to the reaction mixture and the organic phase was separated, washed with water and sat. NaCl solution, dried over Na2SO4 and concentrated to obtain the product 9, which was employed directly as such in the next stage.
