Reaction Steps

2-[(4-Aminocyclohexylcarbonyl)amino]-5-chloro-N-(5-chloropyridin-2-yl)benzamide (300 mg, 0.74 mmol) was diluted with dimethylformamide (8 mL); Potassium carbonate (307 mg, 2.22 mmol) and 1,4-dibromobutane (88 mL, 0.74 mmol) were added. The reaction was heated to 80° C. over the weekend. The reaction was cooled to room temperature, diluted with ethyl acetate (50 mL) and washed with water (5×10 mL). The ethyl acetate layer was dried over sodium sulfate, filtered and concentrated. The crude material was purified by HPLC to give 284 mg (77%) of the title compound as a white solid.
