Procedure
The residue from stage (d) was stirred in DMF at -15° C. for 1 hour with HOBT (2 equiv) and DCCl (1 equiv). To the mixture was added a precooled solution of O-benzylhydroxylamine hydrochloride (1 equiv) and NMM (1 equiv) in DMF and stirring continued for 48 hour at +4° C. The product was filtered, the filtrate concentrated in vacuo, dissolved in ethyl acetate and acid/base washed in the normal manner. The solution was dried (MgSO4), evaporated in vacuo and the residue used the next stage without further purification.
