Procedure
Sodium hydroxide (0.91 g, 0.02 mol) suspended in methanol (15 ml) was added to a stirred solution of Toluene-4-sulfonic acid 2-[(2-hydroxy-propyl)-(toluene-4-sulfonyl)-amino]-ethyl ester (9.69 g, 0.02 mol) in DCM (15 ml). After 1 h, water (50 ml) was added to the solution. The organic layer was collected, dried over sodium sulphate and evaporated in vaccuo to yield a green oily residue. This was purified by chromatographic separation (20% Ethyl acetate:petrol) to yield the title compound as a white solid. (1.70 g, 6.66 mmol, 33%).
