الإجراء التجريبي

3-Amino-azetidine-1-carboxylic acid tert-butyl ester (AstaTech, 1.2 g, 6.97 mmol) and (3-trifluoromethyl-benzoylamino)-acetic acid (Bionet Building Blocks, 1.57 g, 6.36 mmol) were treated with EDCI (Aldrich, 1.57 g, 6.36 mmol), HOBT (Aldrich, 1.22 g, 6.36 mmol) in DCM (10 mL) at room temperature for 4 hours. The reaction solution was partitioned between DCM and water. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated to give a yellow oil, and purified by silica gel column on a CombiFlash® system using hexanes and ethyl acetate (from 10% ethyl acetate to 100% ethyl acetate) to afford the title compound as a white solid.
