Triethylamine → HCID 86686248, compound

Participants

Reaction Steps

4-{1-[3-({[tert-Butyl(dimethyl)silyl]oxy}methyl)-2-fluorophenyl]azetidin-3-yl}piperidine (120 mg) and triethylamine (145 mg) were mixed with dichloromethane (3 ml), and propanoyl chloride (48 mg) was added thereto, followed by stirring at room temperature for 1 hour. A 1 M aqueous NaOH solution and CHCl3 were added to the reaction mixture, and the organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was mixed with THF (3 ml), and a 1 M TBAF/THF (0.5 ml) solution was added thereto, followed by stirring at room temperature for 1 hour. A saturated aqueous ammonium chloride solution and EtOAc were added to the reaction mixture, and the organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (CHCl3/MeOH) to obtain 1-(4-{1-[2-fluoro-3-(hydroxymethyl)phenyl]azetidin-3-yl}piperidin-1-yl)propan-1-one (98 mg).
