Procedure

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(3-formylphenyl)-1H-indole-7-carboxamide (50 mg, 0.114 mmol) in DMSO (3.0 mL) was added O-methylhydroxylamine (57 mg, 0.684 mmol). The reaction was stirred overnight. Additional O-methylhydroxylamine (0.342 mmol) was added to the reaction mixture and stirred for 48 h. The solvent was then concentrated and purified by Gilson Preparatory HPLC to give 29.8 mg of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(3-{[(methyloxy)imino]methyl}phenyl)-1H-indole-7-carboxamide (56%).
