Procedure

To 104 mg (0.026 mmol) of compound 107 was added 6.5 mL of chloroform, 1.3 mL of thionyl chloride, and 100 μL of pyridine. The reaction was allowed to stir at ambient temperature for 3 hours and then all volatiles were removed in vacuo. The residue was stripped in vacuo from chloroform twice. To the resulting solid, suspended in 15 mL of chloroform was added 74 mg (0.028 mmol) of 4-methylphenyl 3-aminobenzenesulfonate (compound 5) and 27 μL (0.033 mmol) of pyridine as a solution in 1.5 mL of chloroform. The reaction was allowed to stir at ambient temperature for 16 hours, after which it was partitioned between ethyl acetate and 1 N HCl (aqueous). The organic layer was dried (magnesium sulfate), filtered, and the volatiles were removed in vacuo. The resulting residue was treated with diethyl ether. and the solid precipitate collected by vacuum filtration. This provided 110 mg of compound 108.
