Reaction Conditions

Reaction Steps

4-bromobenzenesulfonamide (0.37 g, 1.57 mmol) and potassium acetate (0.28 g, 2.87 mmol) were added to a solution of 2-(3-azabicyclo[3.1.0]hexan-3-ylmethyl)-4-(4-chlorophenyl)thiazole (Step-2 of compound 102, 0.42 g, 1.43 mmol) in a DMA (5 ml) in a tube at 25° C. Nitrogen gas was bubbled through the reaction mixture for 15 minutes. Palladium acetate (0.032 g, 0.14 mmol) was then added to the reaction mixture under nitrogen atmosphere and the tube was sealed. The reaction mixture was heated at 150° C. for 20 hrs under stirring. The progress of the reaction was monitored by TLC. The reaction mixture was then cooled to 25° C. and filtered through celite. The celite cake was washed with ethyl acetate (20 ml). The combined filtrate was concentrated under reduced pressure to obtain a crude product, which was then purified by column chromatography using 30% ethyl acetate in hexanes as an eluent to obtain the title compound (0.14 g, 21.4%). MS: m/z 446 (M+1).
