Trifluoroacetic acid → HCID 68196376, compound

Participants

Reaction Steps

Ethyl({[5-(benzyloxy)-2-({1-[2-chloro-4′-(hydroxymethyl)biphenyl-4-yl]piperidin-4-yl}methyl)-6-methylpyrimidin-4-yl]carbonyl}amino)acetate (0.96 g, 1.5 mmol) was dissolved in dichloromethane (20 mL), and trifluoroacetic acid (20 mL) was added under a nitrogen atmosphere, followed by stirring at room temperature for 7 hours. An aqueous sodium hydrogencarbonate solution was added to the reaction solution for neutralization, followed by extraction with dichloromethane, and subsequently the organic layer was concentrated under reduced pressure. The resulting residue was purified by chromatography on a silica gel column (Moritex Corporation, elution solvent: dichloromethane/ethyl acetate), and a fraction corresponding to the Rf value=0.80 (dichloromethane/ethyl acetate=4/1) by thin layer chromatography was concentrated under reduced pressure to afford the title compound (0.74 g, 1.3 mmol) as a yellow oil (yield 90%).
