Procedure

To a solution of [(4-Chloro-benzyl)-(1-{3-[7-(1-hydroxy-1-methyl-ethyl)-11H-10-oxa-1-aza-dibenzo[a,d]cyclohepten-5-ylidene]-propyl}-pyrrolidin-3-yl)-amino]-acetic acid methyl ester (116 mg, 0.2 mmol) in THF:H2O (4:1, 10 mL total volume) was added lithium hydroxide monohydrate (17 mg, 0.4 mmol). The resultant solution was stirred at rt for 3 h. The reaction solution was quenched with 1N HCl and extracted with ethyl ether, dried over MgSO4, filtered and concentrated. The final product was filtered through filter paper and re-concentrated. This product was submitted without further purification.
