Reaction Conditions

Reaction Steps

To a vigorous stirring solution of benzyl (4-oxocyclohexyl)methylcarbamate (1 g) in tetrahydrofuran (20 mL) at −78° C. was slowly added 1 M ethylmagnesium bromide (11.48 ml, 11.48 mmol) in ether. After completion of the addition, the mixture was stirred at −78° C. for 2 hours and was warmed to 0° C., and stirred in an ice bath for 30 minutes. The reaction was quenched with a cold NH4Cl aqueous solution. The precipitates were filtered off and washed with ethyl acetate. The filtrate was concentrated. The residue was dissolved in dichloromethane and loaded onto Analogix purification system, and was eluted with 0-50% ethyl acetate in dichloromethane to provide the title compound.
