Procedure

To a solution of (1R,2R)-1-hydroxy-2-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}sulfonyl)amino]cyclopentanecarboxylic acid (0.08 g) in DMF (0.8 mL) was added hydroxylamine hydrochloride (2 eq), benzotriazol-1-yloxytris(dimethylamino)-phosphonium hexafluorophosphate (1.3 eq) and diisopropylethylamine (4 eq). The reaction was stirred overnight and injected directly onto a reverse phase HPLC (CH3CN/H2O) to afford (1R,2R)-N,1-dihydroxy-2-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}sulfonyl)amino]cyclopentanecarboxamide (0.03 g, 37%) as a white solid. MS: 472.1 (M+H)+
