Procedure

In a vial, (R)-2-(3-(tert-butyldimethylsilyloxy)piperidin-1-yl)-5-(trifluoromethyl)benzenamine (.517 g, 1.4 mmol) was taken up in THF. Triethylamine (0.29 ml, 2.1 mmol) and 2-fluoro-5-iodobenzoyl chloride (0.43 g, 1.5 mmol) were added. The vial was sealed and the reaction stirred for 48 h. The reaction mixture was poured into EtOAc/1N NaOH. The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuo. The crude material was treated with hexanes and passed through a Redi-Sep® pre-packed silica gel column (40 g) eluting with 0-10% EtOAc/hexane. The product-containing fractions were concentrated to afford (R)—N-(2-(3-(tert-butyldimethylsilyloxy)piperidin-1-yl)-5-(trifluoromethyl)phenyl)-2-fluoro-5-iodobenzamide as a white foam.
