(4-chlorophenyl) boronic acid (0.34 g, 2.17 mmol) and potassium carbonate (0.63 g, 4.53 mmol) were added to a solution of 2-(3-azabicyclo[3.1.0]hexan-3-ylmethyl)-4-bromothiazole (Step-1 of compound 102, 0.47 g, 1.81 mmol) in a mixture of toluene:ethanol (5:15 ml) in a tube at 25° C. Nitrogen gas was bubbled through the reaction mixture for 15 minutes. Tetrakis(triphenylphosphine)(0)palladium (0.10 g, 0.09 mmol) was then added to the reaction mixture under nitrogen atmosphere and the tube was sealed. The reaction mixture was heated at 95-100° C. for 18 hr 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 ethanol (20 ml). The combined filtrate was concentrated under reduced pressure to obtain a crude product, which was then purified by column chromatography using 5% ethyl acetate in hexanes as an eluent to obtain the title compound (0.42 g, 79.0%). MS: m/z 291 (M+1).
