A mixture of N-{4-[2-chloro-6-(4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzo[d]thiazol-2-yl}-acetamide (279 mg, 0.6 mmol, Example 7(d)), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1 (2H)-carboxylate (309 mg, 1.0 mmol, ChemShop), PdCl2(PPh3)2 (42 mg, 0.06 mmol, Aldrich), Na2CO3.H2O (74 mg, 0.6 mmol), dimethoxyethane (0.7 mL), H2O (0.3 mL) and EtOH (0.2 mL) was heated in a microwave synthesizer at 120° C. with stirring for 10 min. The reaction mixture was diluted with water (15 mL) and extracted with EtOAc (2×30 mL). The combined organic phases were washed with brine (20 mL), dried over Na2SO4 and filtered. The filtrate was evaporated in vacuo and the residue was purified by silica gel column chromatography (30% EtOAc/hexane) to give the title compound. MS (ESI, pos. ion) m/z: 612 (M+1).
