Reaction Steps

A mixture of 10% Pd-C 50% wet (20 mg) and N-(2-{4-[3-isopropenyl-1-(6-methoxy-3-pyridinyl)-1H-pyrazol-5-yl]phenoxy}ethyl)methanesulfonamide (118 mg) in THF (1 ml) and MeOH (1 ml) was hydrogenated under H2 1atm at ambient temperature for 1 day. The catalyst was removed by filtration. The filtrate and combined washings were concentrated in vacuo. The residue was purified by preparative thin layer silica gel chromatography developed by AcOEt/n-hexane=70%. The separated silica gel was extracted with 10% MeOH/CHCl3 and the solvent was evaporated in vacuo. The residue was recrystallized from AcOEt-IPE to give N-(2-{4-[3-isopropyl-1-(6-methoxy-3-pyridinyl)-1H-pyrazol-5-yl]phenoxy}ethyl)methanesulfonamide (68.6 mg) as white powder.
