Reaction Steps

A suspension of 4-(1-benzyl-3,4-dihydro-2H-pyridin-5-yl)-6-(3,3-difluoropyrrolidin-1-yl)-N-[4-(trifluoromethyl)-2-pyridyl]pyridin-2-amine (250 mg, 0.4850 mmol) and palladium hydroxide on activated charcoal (85 mg, 0.25 equiv., 0.1212 mmol) in methanol (20 ml, 500 mmol) and ethyl acetate (20 ml, 204 mmol) was charged with H2 balloon. The reaction was kept stirring for 48 h, while LCMS indicated olefin was reduced. The catalyst was filtered off, and new portion of catalyst was refilled, followed by addition of acetic acid (0.556 mL, 20 equiv., 9.699 mmol). The reaction was stirred with H2 balloon overnight. LCMS showed both m/z 442 and 456. The catalyst was filtered off, and the solvent was evaporated to dryness. The residue was submitted for HPLC purification to yield 4.7 mg (4.4%) off-white powder. LCMS: m/z 442 (M+H).
