Reaction Steps

A mixture of 5-amino-6-bromo-4-nitroindane-2-carboxylic acid (5.5 g, 18 mmol) and 20% Pd/C (0.5 g) in 95% ethanol (250 mL) and tetrahydrofuran (250 mL) was shaken on a Parr hydrogenation apparatus under a hydrogen atmosphere (51 psi) for 30 h. After removing the catalyst, the solvent was evaporated to give a solid. The solid was dissolved in 2N HCl (150 mL) and treated with oxalic acid (4.6 g), and then the mixture was heated at 90° C. for 5 h. After cooling to room temperature, the precipitate was collected by filtration and dried in vacuo (4.0 g).
