Procedure
A mixture of 2-Chloro-N-[4-(1-cyclobutyl piperidin-4-yloxy)phenyl]acetamide (76.0 g, 0.236, obtained in above step), morpholine (30.8 g, 0.353 moles) and potassium carbonate (98 g, 0.71 moles) in acetonitrile (1.5 L) was stirred for 5 hours at reflux temperature. The mixture was partitioned between ethyl acetate (1 L) and water (1 L). The layers were separated, and the aqueous layer was extracted with ethyl acetate (2×500 mL). The combined organic layers were washed with water twice, dried over sodium sulfate and concentrated under vacuum. The crude compound was purified by flash chromatography using (methanol:chloroform, 2:8) to afford the title compound 71 g (Yield: 80%).
