To the solution of 2,2,2-trifluoro-N-(trans-2-phenylcyclopropyl)-N-(piperidin-4-ylmethyl)acetamide (60 mg, 0.184 mmol) in acetonitrile (10 mL) was added potassium carbonate (76 mg, 0.552 mmol) followed by 2-bromoethanol (29.9 mg, 0.239 mmol). The reaction mixture was heated in the seal tube at 80° C. for 4 hours. The reaction mixture was then filtered and evaporated. 2,2,2-Trifluoro-N-((1-(2-hydroxyethyl)piperidin-4-yl)methyl)-N-(trans-2-phenylcyclopropyl)acetamide (40 mg, 0.103 mmol, 55.8% yield) was isolated as yellow oil. 1H NMR (400 MHz, METHANOL-d4) δ 7.07-7.37 (m, 5H), 3.75-3.87 (m, 2H), 3.57-3.66 (m, 1H), 3.49-3.57 (m, 1H), 3.46 (t, J=6.06 Hz, 1H), 3.36-3.41 (m, 3H), 3.19 (t, J=3.79 Hz, 1H), 2.78-3.04 (m, 2H), 2.56-2.76 (m, 1H), 2.48 (ddd, J=3.54, 6.51, 10.17 Hz, 1H), 1.96-2.15 (m, 1H), 1.87 (td, J=2.91, 10.80 Hz, 2H), 1.63 (dt, J=5.24, 10.23 Hz, 1H), 1.39-1.57 (m, 3H); LC-MS Rt=0.76 min; MS (ESI): 371.2 [M+H]+.
