Procedure

A solution of 0.40 g (1.10 mmol) of 1-{3-[(E)-2-(4-chloro-phenyl)-vinyl]-phenyl}-3,5-diethyl-1H-pyrazole-4-carboxylic acid (intermediate 1) and 0.18 g (1.1 mmol) of 2-chloro-4,6-dimethoxy-[1,3,5]triazine were dissolved in 10 ml of MeCN. The solution was then cooled down to 0° C. and 0.32 g=0.35 ml (3.2 mmol) of N-methylmorpholine was added drop by drop. After 2 hours stirring at 0° C., a solution of 0.21 g (1.1 mmol) 1-(1-methyl-piperidin-4-ylmethyl)-piperazine in 3 ml of MeCN was added drop by drop. Then, the mixture was warmed up to RT and stirring continued for 20 hours. Subsequently, it was poured into crashed ice and extracted twice with EtOAc; the organic phases were washed with water, dried over magnesium sulfate, filtered and evaporated. The residue was purified by flash column chromatography (CH2Cl2/MeOH 1:0-7.5:2.5) to afford the title compound as colorless solid. MS: 560.2 (MH+, 1 Cl).
