    摘要： A process for the preparation of a compound of formula (I) and pharmaceutically acceptable derivatives thereof in which: R0 is halogen, C1-6alkyl, C1-6alkoxy, C1-6alkoxy substituted by one or more fluorine atoms, or O(CH2)nNR4R5; R1 and R2 are independently selected from H, C1-6alkyl, C1-6alkyl substituted by one or more fluorine atoms, C1-6alkoxy, C1-6hydroxyalkyl, SC1-6alkyl, C(O)H, C(O)C1-6alkyl, C1-6alkylsulphonyl, C1-6alkoxy substituted by one or more fluorine atoms, O(CH2)nCO2C1-6alkyl, O(CH2)nSC1-6alkyl, (CH2)nNR4R5, (CH2)nSC1-6alkyl or C(O)NR4R5; with the proviso that when R0 is at the 4-position and is halogen, at least one of R1 and R2 is C1-6alkylsulphonyl, C1-6alkoxy substituted by one or more fluorine atoms, O(CH2)nCO2C1-6alkyl, O(CH2)nSC1-6alkyl, (CH2)nNR4R5 or (CH2)nSC1-6alkyl, C(O)NR4R5; R3 is C1-6alkyl or NH2; R4 and R5 are independently selected from H, or C1-6alkyl or, together with the nitrogen atom to which they are attached, form a 4-8 membered saturated ring; and n is 1-4.
