Reaction Steps

Pd/C (175 mg, 10% weight Pd on carbon) was added to a round bottom flask and the flask was flushed with N2. To this flask was then added MeOH (10 mL). After purging the flask again with N2, (S)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperidin-3-ylcarbamate (1.75 g, 3.74 mmol) dissolved in EtOAc (60 mL) and MeOH (50 mL) was added. After flushing the flask 3 times with N2, and evacuating it under vacuum, H2 was passed through the vigorously stirring mixture for 4 h until hydrogenation was complete. The mixture was filtered through a pad of Celite. The filtrate was concentrated to afford 2-(4-((S)-3-aminopiperidin-1-yl)-7-methylquinazolin-2-yl)phenol (0.62 g, 50%). LC/MS: m/z 335.5 (M+H)+ at 1.50 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
