Reaction Steps

1-(3,3-Dimethyl-6-nitro-2,3-dihydro-indol-1-yl)ethanone (1.8 g) was dissolved in 50 mL EtOH, 50 mL 12N HCl was added and the resulting mixture was heated at 70° C. overnight. After the mixture was concentrated in vacuo, it was extracted between saturated NaHCO3 solution and EtOAc. The resulting organic layer was dried over MgSO4, filtered and concentrated in vacuo to afford a yellow solid. MS: 193 (M+1). Calc'd. for C10H12N2O2—192.2.
