Reaction Steps

tert-Butyl 4-[4-(5-chloro-2-hydroxyphenyl)pyrimidin-2-yl]piperazine-1-carboxylate (Preparation 2, 48.6 mg, 0.11 mmol), tert-butyl[(5-chloro-2,4-difluorophenyl)sulfonyl]1,3-thiazol-4-ylcarbamate (Preparation 4, 43.6 mg, 0.11 mmol) and potassium carbonate (21.9 mg, 0.16 mmol) were mixed in dimethylsulfoxide (1 mL) and shaken at ambient temperature for 18 hours. The reaction mixture was diluted with water and the precipitate collected by filtration. The solid was dissolved in dichloromethane (2.0 mL) and dried over anhydrous magnesium sulfate. The mixture was filtered and trifluoroacetic acid (0.060 mL, 0.78 mmol) was added to the filtrate. After 2 hours the reaction mixture was concentrated in vacuo to a residue and purified by reverse phase HPLC to afford the title compound as a tan glass (55 mg).
