実験手順
To a solution of 1,1-dimethylethyl((1R)-1-{[(6-{[4-cyano-3-(1-methylethenyl)phenyl]oxy}-3-pyridinyl)amino]carbonyl}propyl)carbamate (Intermediate 178, 73 mg) in MeOH (10 mL) was added Pd 10% w/w on activated carbon (14 mg) and the reaction mixture was stirred for 30 minutes under H2 atmosphere (P=1 atm). The catalyst was filtered off and the solvent removed under reduced pressure. The residue was purified by flash chromatography on silica gel (SNAP 10 g) eluting from 75:25 to 40:60 cyclohexane/ethyl acetate affording the title compound (62 mg) as white solid.
