Reaction Steps

The title compound was prepared following procedure described for example 4, step 1, but starting from Intermediate 28 (128.15 mg; 0.5 mmol) and methyl 3-[(E)-amino(hydroxyimino)methyl]benzoate, prepared as described in US2004/204461 from methyl 3-cynaobenzoate (Maybridge; RJC00610EA), (97 mg; 0.5 mmol). The reaction mixture was filtered through a SPE NH2 column (2 g) and rinsed with ACN. The filtrate was passed through a SPE SCX column (2 g) and rinsed with ACN. After evaporation of the solvents, the crude product was purified by FC (c-hex/EtOAc: 9.5/0.5 to 5/5). It was then suspended in MeCN and filtrated, affording the title compound as a white solid. LC/MS (Method B): 415.2 (M+H)+. HPLC (Method A) Rt 6.48 min (Purity: 96.2%).
