Procedure: To a stirred suspension of LAH (6.1 mmol) in THF (25 mL) is added dropwise a solution of 2-amino-1-morpholin-4-yl-2-phenylethanone (670 mmol) in THF (5 mL) at 0° C. The reaction mixture is refluxed for 2 hr, and then the reaction is quenched by the addition of Na2SO4-10H2O at 0° C. After stirring at room temperature for 0.5 h, the resulting mixture is filtered through celite, and the filtrate is concentrated in vacuo to give the title compound, which is directly used for the next reaction without further purification. The reaction mixture is refluxed for 2 hr the reaction is quenched by the addition of Na2SO4-10H2O at 0° C the resulting mixture is filtered through celite the filtrate is concentrated in vacuo

Procedure: To a solution of (2-morpholin-4-yl-2-oxo-1-phenylethyl)carbamic acid tert-butyl ester (3.0 mmol) in CH2Cl2 (6.0 mL) is added TFA (2.0 mL) at 0° C. After stirring at room temperature for 24 h, the reaction mixture is basified to pH 8 with sat. aq NaHCO3. The mixture is extracted with CH2Cl2, and then the combined organic extracts are dried over Na2SO4 and concentrated in vacuo to give the title compound; 1H NMR (CDCl3) δ 2.02 (s, 2H), 3.09-3.14 (m, 1H), 3.20-3.25 (m, 1H), 3.34-3.40 (m, 1H), 3.46-3.60 (m, 3H), 3.65-3.71 (m, 1H), 3.74-3.80 (m, 1H), 7.27-7.34 (m, 5H). The mixture is extracted with CH2Cl2 the combined organic extracts are dried over Na2SO4 concentrated in vacuo
