Procedure
A mixture of 3-(naphthalene-1-sulfonyl)-1H-indazole-5-carbaldehyde (0.15 g, 0.44 mmoles) and KMnO4 (0.03 g, 0.29 moles) was stirred in CH3CN/H2O (4:1) for 1 hour. Reaction mixture was acidified with 2N HCl, stirred with saturated sodium bisulfite for 10 minutes, then extracted with EtOAc, dried over Na2SO4 and concentrated in vacuo to afford the title compound (0.13 g, 3.9 mmoles).
