Procedure
Methyl 8-amino-6-(3-pyridylmethyl)-octanoate (0.5 g) is dissolved in 50 mL of methylene chloride and 3 mL of triethylamine is added. To this solution is added dropwise a solution of 0.5g of p-chlorobenzenesulfonyl chloride in 10 mL of methylene chloride. The reaction is stirred at room temperature for 1 hour, the solvent is evaporated and the residue thus obtained purified by chromatography over silica gel, using methylene chloride as eluent to obtain methyl 8-(p-chlorophenylsulfonamido)-6-(3-pyridylmethyl)-octanoate as an oil.
