Reaction Steps

0.85 g (2.00 mmol) of 3{[tert-Butoxycarbonyl-(2,4-dichloro-benzyl)-amino]-methyl}-benzoic acid methyl ester was dissolved in 20 ml of dioxan. 5 ml of water and 2N aqueous NaOH was added to the solution to give a pH of 13. The reaction solution was stirred for 5 h then poured into water. The resulting solution was cooled to 0° C. and concentrated hydrochloric acid was added to give a pH of 3. The product was extracted 3 times with ethyl acetate. The organic phase was dried over magnesium sulphate, filtered and the solvent was removed under reduced pressure.
