Zusammenfassung:Disclosed are 5-amino-phenol derivatives as represented by the general formula A-I which are useful intermediates in the preparation of ATP-binding cassette transporters, wherein G1 is hydrogen, R', C(O)R', C(S)R', S(O)R', S(O)2R', Si(CH3)2R', P(O)(OR')3, P(S)(OR')3, or B(OR')2; G2 is halo, CN, CF3, isopropyl, or phenyl wherein said isopropyl or phenyl is optionally substituted; G3 is an isopropyl or a cycloaliphatic ring, wherein said G3 is optionally substituted; and wherein the remaining substituents are as defined herein. Representative compounds of the formula A-I include 2-tert-butyl-5-amino-4-fluorophenol, 2-tert-butyl-5-amino-4-chlorophenol and 5-amino-2,4-di-tert-butyl-phenol.
