Procedure

Bis-(4-nitrobenzenesulfonyl)-tetraethylene glycol (10 g, from Part A) was dissolved in distilled ethyl acetate (200 ml) and hydrogenated over palladium on carbon (10%, 0.5 g) at 40 p.s.i. in a Parr hydrogenation apparatus. The solution was filtered and evaporated under reduced pressure to give bis-(4-aminobenzenesulfonyl)-tetraethylene glycol in quantitative yield as a thick, yellow oil which was homogeneous by TLC.
