To a DMF 10 mL solution of 1-(1,3-dioxolan-2-yl)-N-{[7-(trifluoromethyl)imidazo[1,2-a]pyridin-2-yl]methyl}methanamine (1.13 g, 3.75 mmol) were added 4-(2,4,6-trifluorobenzoyl)-1H-pyrrole-2-carboxylic acid (1.06 g, 3.94 mmol), EDC (1.08 g, 5.63 mmol), HOBt (862 mg, 5.63 mmol) and triethyl amine (1.57 mL, 11.25 mmol). The mixture was stirred at room temperature overnight. The resulting suspension was diluted with EtOAc. The organic phase was washed with sat. ammonium chloride aq., sat. aq. sodium bicarbonate aq. and brine, dried over anhydrous Na2SO4, filtered, concentrated and chromatographed on silica gel eluting with a gradient solvent mixture (100% DCM to 5% MeOH-DCM) to give the title compound as foam (744 mg). LC/MS: m/z 533(M+H).
