To a solution of 1-[4-(3-amino-5-chloro-pyridin-2-yl)-piperazin-1-yl]-2-(3,5-dimethyl-pyrazol-1-yl)-ethanone (0.040 g, 0.11 mmol) in methylene chloride (2 mL) is added 3-chlorobenzoyl chloride (0.020 mL, 0.160 mmol) followed by of N,N-diisopropylethylamine (0.045 mL, 0.25 mmol). The mixture is stirred at room temperature for 3 days. The mixture is concentrated under a stream of nitrogen and the residue is purified by preparative reverse phase HPLC to provide, after removal of the eluent under reduced pressure, 0.030 g of 3-chloro-N-(5-chloro-2-{4-[2-(3,5-dimethyl-pyrazol-1-yl)-acetyl]-piperazin-1-yl}-pyridin-3-yl)-benzamide as a white solid in 53% yield.
