Procedure

Combine 6-(2-benzyl-2,3-dihydro-1H-isoindol-5-yloxy)-nicotinamide (230.0 mg, 0.67 mmol), EtOH (5 mL), and 10% Pd—C (45.0 mg) and place under a hydrogen balloon. Stir the reaction at room temperature for 168 hours at atmospheric pressure. Filter the reaction mixture through a pad of Celite® using MeOH eluent and then concentrate the filtrate under reduced pressure. Add the mixture to a 2 g SCX column, wash with MeOH, and elute using 1.0 N NH3—MeOH. After concentrating under reduced pressure, purify the mixture by flash chromatography using 10% 1.0 N NH3-MeOH/DCM eluent to afford 19.2 mg, 0.08 mmol (11% yield) of the title compound as a white solid: 1H NMR (500 MHz, CD3OD); 4.1-4.3 (4H, br m), 6.9-7.1 (3H, m), 7.3-7.4 (1H, m), 8.2-8.3 (1H, m), 8.6 (1H, s); MS m/z 254 (M−1).
