Reaction Steps

A 100 mL Parr reaction vessel is charged with 2-(Isoquinolin-5-ylcarbamoyl)-indan-2-carboxylic acid ethyl ester (320, 500 mg, 1.39 mmol) and EtOH (10 mL). The reaction vessel is agitated by swirling until dissolution ° C. curred. Acetic acid (10 mL) and platinum (IV) oxide (117 mg, 0.52 mmol) are added. The vessel is fitted on a Parr hydrogenation apparatus, flushed with N2 and then evacuated. The vessel is charged with hydrogen to 50 psi. The apparatus is set to agitate. After 4 h, agitation is ceased. The reaction vessel is evacuated and flushed with nitrogen. This process is repeated. The contents of the reaction vessel are diluted with iPrOH (50 mL) and filtered through a pad of celite. Solvent is removed from the filtrate under reduced pressure. The resulting residue is reconstituted in iPrOH (15 mL) and toluene (15 mL). The solvent is removed under reduced pressure. This process is repeated. Pumping to constant weight yields light beige solid (0.5 g, 99%).
