Reaction Steps

To a solution of (R*)-3-{1-[(S)-1-(2,3-dihydrobenzo[1,4]dioxin-2-yl)methyl]piperidin-3-yl}phenol (201 mg, 0.62 mmol) in dry DMF (2 ml) was added NaH (60% in oil, 30 mg, 0.75 mmol) under nitrogen atmosphere and the mixture was stirred at 0° C. for 5 min, then allowed to warm to RT and stirred for further 2.5 h. The reaction mixture was cooled to 0° C., ethyl bromoacetate (106 mg, 0.62 mmol) was added and the mixture was stirred at RT overnight. Potassium tert-butoxide (69 mg, 0.61 mmol) was added and the mixture was stirred for 3 h at RT and filtered. The precipitate was dissolved in dry MeOH, the solution filtered and evaporated to dryness to give 170 mg of the title compound.
