Conditions

Temperature: 110 °C

Procedure

2-{2-[1-(5-chloropyrimidin-2-yl)piperidin-4-yl]cyclopropyl}ethanamine from step 3 of this example (50 mg, 0.178 mmol) was in 0.594 mL NMP. 1-fluoro-4-(methylsulfonyl)benzene (37.2 mg, 0.2141 mol) and DBU (0.040 mL, 0.267 mmol) were sequentially added. The reaction mixture was stirred at 110° C. overnight before cooled back to room temperature. The reaction mixture was diluted with water and aqueous phase was further extracted with ethyl acetate for 3 times. The combined organic layers were washed with water and brine, then dried over Na2SO4 and concentrated. The residue was purified by column chromatography using gradient elution (0 to 65% ethyl acetate in hexane) to give the titled compound. LRMS calc: 434.9; obs: 435 (M+1).
