Participants

Reaction Steps

To a solution of 4-(4-methylsulfonylaminophenoxy)benzaldehyde (2.50 g) in dimethyl formamide (25 mL) were added 4-hydroxypiperidine (1.74 g) and acetic acid (2.5 mL), and the solution was stirred. To the reaction solution was added sodium triacetoxyborohydride (2.18 g) and the solution was stirred for 2 days. After finishing the reaction, the reaction solution was neutralized with 2N aqueous solution of sodium hydroxide and extracted with ethyl acetate. The organic layer was washed with brine, dried over magnesium sulfate and concentrated. The obtained residue was purified by column chromatography on silica gel (methylene chloride:methanol=10:1) to give the title compound (1.90 g) having the following physical data.
