Trifluoroacetic acid → HCID 59759199, compound

Participants

Reaction Steps

A compound obtained using {2-[(2-tert-butoxy-1,1-dimethyl-2-oxoethyl)thio]-1,3-thiazol-4-yl}acetic acid synthesized in Example 3 and 2-aminopyridine as starting materials and by an operation similar to that of Example 293-1 was treated with dichloromethane and trifluoroacetic acid and the mixture was stirred at room temperature for 12 hr. The reaction solution was concentrated under reduced pressure, and the residue was purified by high performance liquid chromatography (elution solvent; 0.05% trifluoroacetic acid-water:0.05% trifluoroacetic acid-acetonitrile=85:15 to 40:60) to give the title compound as a white solid.
