Procedure

A solution of 0.20 g (0.50 mmol) of 1-{3-[(E)-2-(4-chloro-phenyl)-vinyl]-phenyl}-3,5-diethyl-1H-pyrazole-4-carboxylic acid (intermediate 1) and 0.21 g (0.50 mmol) of HATU were dissolved in 8 ml of DMF at RT. While stirring, 0.16 g=0.22 ml (1.60 mmol) of Et3N were added drop by drop. After 30 min, a solution of 0.076 g (0.50 mmol) of 2-[1,4]diazepan-1-yl-ethanol in 2 ml of DMF were added drop by drop and stirring was continued for 20 hours at RT. The reaction mixture 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 1:0-9:1) to afford the title compound as colorless oil. MS: 507.4 (MH+, 1 Cl).
