Reaction Conditions

Reaction Steps

To a flask containing 5-(3,6-dihydro-2H-pyran-4-yl)pyridin-3-amine (61.6 mg, 0.35 mmol) in EtOAc (3.0 mL) and EtOH (1.0 mL) was added 10% palladium on activated carbon (75.7 mg, 0.071 mmol). After purging, the mixture was stirred under an atmosphere of hydrogen at 23° C. The reaction was monitored with TLC and LC-MS. After 19 h, the reaction was filtered through Celite™. After concentration, the residue was identified as 5-(tetrahydro-2H-pyran-4-yl)pyridin-3-amine that was used without purification. Mass Spectrum (pos.) m/e: 179.1 (M+1).
