N-{2-[5-(4-Chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl]pyridin-5-yl}amine (0.3 g, 0.88 mmol) and methylisothiocyanate (0.3 ml, 4.4 mmol) were dissolved in THF and the reaction mixture was stirred at 60° C. overnight. The mixture was diluted with ethyl acetate and washed with 1N HCl, 10% sodium bicarbonate, water, and brine. The solvents were removed in vacuo and the crude product was purified by flash chromatography (ethyl acetate-methanol, 97:3) to give 1-{2-[5-(4-chlorobenzoyl)-1,4-dimethyl-1H-pyrrol-2-ylmethyl]pyridin-5-yl}-3-methyl-2-thiourea (265 mg, 73%) as a solid, mp 135° C.
