Reaction Steps

tert-Butyl 4-(3-(2-fluorophenyl)-2-oxo-2,3-dihydroimidazol-1-yl)piperidine-1-carboxylate (530 mg, 1.5 mmol) was dissolved in methanol (25 mL). Platinum(IV) oxide (28 mg, 123.3 Emoles) was added to the mixture. Reaction vessel was placed on a Parr apparatus and charged with 60 psi of hydrogen gas. Reaction shook at room temperature for 4 hours. More platinum(IV) oxide (28 mg, 123.3 μmol) was added to the mixture. Reaction vessel was placed on a Parr apparatus and charged with 60 psi of hydrogen gas. Reaction shook at room temperature for 18 hours. Mixture was removed from the apparatus and then filtered over celite. The filtrate was concentrated by roto-vap. Silica gel chromatography eluting ethyl acetate-hexanes afforded the title compound as clear colorless oil in 45% yield. MS (M−C4H10O+H)+=290.0.
