Reaction Steps

A mixture of 5-Iodo-2-(4-methyl-pyridin-3-yl)-imidazo[2,1-b][1,3,4]thiadiazole (18 mg, 0.053 mmol, 1 eq), 5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-3-trifluoromethyl-pyridin-2-ylamine (20 mg, 0.068 mmol, 1.3 eq), Pd(PPh3)2Cl2 (9 mg, 0.011 mmol, 0.2 eq) and sat aq K2CO3 (0.22 mL) in DME (0.5 mL) was heated under microwave irradiation at 120° C. for 30 min. On cooling, DCM was added and the mixture was washed with water. The organic layer was dried (Na2SO4), filtered and evaporated. The residue was purified by column chromatography (DCM/MeOH 95:5) to afford the desired product (8 mg, 40%). HPLC-MS (5-100% B in 8 min at 0.8 mL): tR=4.32 min, [M+H]+ m/z 377.1; 1H NMR (300 MHz, CDCl3) δ 8.80 (s, 1H), 8.70 (s, 1H), 8.55 (d, J=5.0 Hz, 1H), 8.31 (s, 1H), 7.56 (s, 1H), 7.28 (d, J=5.0 Hz, 1H), 5.39 (s, 2H), 2.63 (s, 3H).
