Procedure

A mixture of N-{4-[3-cyano-4-(2,4-dichlorophenyl)-5-(4,5-dihydro-1H-imidazol-2-yl)-2-thienyl]pyridin-2-yl}cyclopropanecarboxamide (0.0650 g, 0.135 mmol) and Magtrieve (0.143 g, 1.70 mmol) was taken up in toluene (5 mL) and heated at 120° C. for 4 hours. The mixture was cooled to room temperature, diluted with DCM (10 mL) and filtered through a pad of celite. The solid residue was washed with 1% ammonia, 9% methanol in DCM mixture (10 mL) and solvent from the filtrate was evaporated. The residue was purified using ISCO chromatography on silica gel, elution 10 to 70% ethyl acetate in hexanes to afford the product (0.027 g, 47%). LCMS: (FA) ES+, 480, 482. 1H NMR (400 MHz, d6-DMSO) δ: 11.88 (s, 1H) 11.11 (m, 1H), 8.57-8.55 (m, 1H), 8.53-8.50 (m, 1H), 7.85-7.84 (m, 1H), 7.58-7.56 (m, 2H), 7.54-7.52 (m, 1H), 7.17-7.16 (m, 1H), 7.00-6.98 (m, 1H), 2.08-2.00 (m, 1H), 0.87-0.81 (m, 4H).
