Versuchsvorschrift

Prepared using General Procedure 19: To a stirring solution of tert-butyl 2-(N-(4-cyanobenzyl)-4-(2-(4-methoxy-2-(trifluoromethyl)phenyl)acetamido)benzamido)acetate INT-32 (229 mg, 0.394 mmol) in DMF (3 mL) were added triethylamine (142 μl, 0.984 mmol) and hydroxylamine hydrochloride (68.4 mg, 0.984 mmol). After stirring at room temperature for 72 h, the reaction mixture was diluted with water (50 mL) and extracted with DCM (3×20 mL). The organics were dried over MgSO4 and evaporated. The crude product was purified by column chromatography (MeOH/DCM) to yield 107 mg (44%) of tert-butyl 2-(N-(4-(N-hydroxycarbamimidoyl)benzyl)-4-(2-(4-methoxy-2-(trifluoromethyl)phenyl)acetamido)benzamido)acetate INT-33. LCMS-ESI (m/z) calculated for C31H33F3N4O6: 614; found 615 [M+H]+, tR=1.70 min (Method 10).
