A method for forming an optionally substituted 2-aminobenzoxazole compound includes: contacting an optionally substituted 2-aminophenol compound with (1) an amine of the formula NHR2R3, wherein R2 and R3 are each independently selected from H, an optionally substituted alkyl group or an optionally substituted aryl group, or R2 and R3, taken together with the nitrogen atom to which they are attached, form an optionally substituted heterocyclic ring; and (2) a reactant selected from the group consisting of: (a) C(OR)4, wherein R represents an alkyl group; (b) C(OAr)4, wherein Ar represents an aryl group; and (c) CCl2(OAr)2, wherein Ar represents an aryl group, in combination with a base; thereby forming the optionally substituted 2-aminobenzoxazole compound.

The synthesis of 2-aminobenzoxazoles can be readily achieved by two versatile, one-pot procedures utilizing commercially available tetramethyl orthocarbonate or 1,1-dichlorodiphenoxymethane, an amine, and an optionally substituted 2-aminophenol. The reactions were conducted under mild conditions and provided 2-aminobenzoxazoles in modest to excellent yields. A variety of amines and substituted 2-aminophenols
