실험 절차

Prepared using General Procedure 7. To a stirring solution of methyl 2-amino-2-(4-bromophenyl)acetate (421 mg, 1.5 mmol), 4-(tert-butyl)benzoic acid (321 mg, 1.8 mmol), and DIEA (831 μl, 4.5 mmol) in DMF (3 mL) cooled to 0° C. was slowly added a solution of HATU (380 mg, 1.65 mmol) in DMF (1.5 mL) in a drop-wise fashion. The reaction mixture was allowed to warm slowly and stirring continued for 4 h. The reaction mixture was poured onto ice-water and the solid was filtered. The solid was dissolved in DCM (10 mL), dried over MgSO4 and evaporated to afford 532 mg (88%) of methyl 2-(4-bromophenyl)-2-(4-(tert-butyl)benzamido)acetate. LCMS-ESI (m/z) calculated for C20H22BrNO3: 403.0. found 404.1 [M+H]+, tR=3.61 min. (Method 16).
