実験手順

A mixture of 6-benzyl-4-methoxy-2-(5-methyl-1-tosyl-1H-indazol-4-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (1.85 g, 3.43 mmol) and Pd(OH)2 on carbon (wet) (10%, 0.722 g, 1.03 mmol) in water (7.5 mL) and acetic acid (0.59 mL) was stirred under 1 atm of hydrogen at room temperature for 2.5 h. The reaction mixture was filtered through Celite® and the solids were washed with EtOAc. The combined filtrates were washed with saturated NaHCO3 solution. The layers were separated and the aqueous layer was extracted with EtOAc. The combined organics were washed with brine, dried (Na2SO4) and concentrated. The residue was purified by silica gel chromatography (0-10% MeOH (10% NH4OH)/DCM) to provide 4-methoxy-2-(5-methyl-1-tosyl-1H-indazol-4-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. MS (ESI+) m/z 450.1 (M+H)+.
