Trifluoroacetic acid → HCID 135729082, compound

Participants

Reaction Steps

Trifluoroacetic acid (0.10 mL, 1.3 mmol, Aldrich) was added dropwise to a solution of N-{4-[6-(2-methoxymethoxy-4-trifluoromethyl-phenyl)-pyrimidin-4-yloxy]-benzothiazol-2-yl}-acetamide, (Example 136(b)), (0.50 g, 1.0 mmol) in dichloromethane (10 mL) with stirring and cooling in an ice bath. The reaction mixture was stirred for 16 h at room temperature, diluted with dichloromethane (5 mL) and quenched with satd sodium bicarbonate solution. The reaction mixture was diluted with water (100 mL), extracted with dichloromethane (2×100 mL), and the combined organic extracts were concentrated in vacuum. The resulting white solid was suspended in MeOH (50 mL), collected by filtration, and dried under vacuum to obtain the title compound as a white solid. Mp: 302–304° C. MS (ESI, pos. ion.) m/z: 445 (M+1).
