Reaction Conditions

Reaction Steps

After dissolving 148 mg of 2-fluorophenol in 10 mg of dimethylformamide, 53 mg of sodium hydride (70% suspension in oil) was added, the mixture was stirred at 80° C. for 30 minutes, a solution of 148 mg of 7-(tert-butoxycarbonyl)-2-methanesulfonyloxy-7-azaspiro[3.5]nonane in N,N-dimethylformamide (7 ml) was added and the mixture was stirred at 80° C. for two nights. After cooling it to room temperature, water was added and extraction was performed with ethyl acetate. The organic layer was washed with a 1N sodium hydroxide solution and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain the title compound (163 mg, 100% yield).
