Procedure

7.20 g (17.5 mmol) of 2-(3-hexyl-phenyl)-5-iodo-3-methyl-3H-imidazole-4-carboxylic acid (intermediate 1) were dissolved in 290 ml of DMF and treated with 6.846 g (17.5 mmol) of HATU. 7.30 ml=5.30 g (52.4 mmol) of Et3N were added and after 30 min, a solution of 2.72 g (17.5 mmol) of 4-pyrrolidin-1-yl-piperidine in 70 ml of DMF was added. After 16 hours, the reaction mixture was poured into crashed ice and extracted three times with Et2O; 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 to 9:1) to give 8.65 g (90%) of the title compound as light brown foam. MS: 549.3 (MH+).
