Reaction Steps

To a mixture of methyl 3-[(E)-(hydroxyimino)methyl]-1H-indole-2-carboxylate (from Key Organics, 1.0 g, 4.6 mmol) and pyridine (7.4 mL, 92 mmol) in 1,4-dioxane (20 mL) was added methanesulfonyl chloride (1.4 mL, 18 mmol). The reaction was heated at 60° C. for 2 hours. The reaction was diluted with water and extracted with EtOAc. The combined organic layers were dried over MgSO4, concentrated, and purified on silica gel (eluting with 0-5% MeOH/dichloromethane) to give the desired product (0.7 g, 76%). LCMS calculated for C11H9N2O2(M+H)+: m/z=201.1. Found: 201.1.
