200 mg of [3-(2-p-tolylimidazo[1,2-a]pyridin-6-yl)phenyl]methanol (Example 3) are dissolved in 20 ml of dry tetrahydrofuran, 123 mg of p-chlorophenol, 193 mg of tributylphosphine and 210 mg of 1,1′-azodicarbonyldipiperidine are added thereto and the mixture is left to stir at ambient temperature for 16 h. The solvent is evaporated off under reduced pressure. The residue is taken up with 10 ml of ethyl acetate, the precipitate is removed, the filtrate is concentrated and the residue is purified by chromatography. The solid obtained is taken up with petroleum ether and the precipitate is recovered by filtration and dried under reduced pressure. 52 mg of compound are obtained. Mp=182-184° C. 1H NMR (DMSO-d6, δ in ppm): 2.32 (s, 3H); 5.17 (s, 2H); 7.06 (d, J=7 Hz, 2H); 7.23 (d, J=7.2 Hz, 2H); 7.32 (d, J=7.3 Hz, 2H); from 7.40 to 7.80 (m, 6H); 7.84 (m, J=7.8 Hz, 2H); 8.32 (s, 1H); 8.86 (m, 1H). M+H=425.
