Process for preparing substituted quinolin-4-ol compounds

A process for preparing a compound of Formula (I),

• wherein:
• each R is independently F, Cl, Br, I, CN, (C1-C6)alkyl, ORa, or NRbRc;
• n is 0, 1, 2, 3, or 4;
• each of Ra, Rb and Rc is independently H, (C1-C6)alkyl, (C3-C6)cycloalkyl, —(C1-C4)alkylene-(C3-C6)cycloalkyl, 3-6 membered heterocyclyl, —(C1-C4)alkylene-(3-6 membered heterocyclyl), (C6-C10)aryl, —(C1-C4)alkylene-(C6-C10)aryl, 5-10 membered heteroaryl, or —(C1-C4)alkylene-(5-10 membered heteroaryl), wherein each of the (C1-C6)alkyl, (C3-C6)cycloalkyl, —(C1-C4)alkylene-(C3-C6)cycloalkyl, 3-6 membered heterocyclyl, —(C1-C4)alkylene-(3-6 membered heterocyclyl), (C6-C10)aryl, —(C1-C4)alkylene-(C6-C10)aryl, 5-10 membered heteroaryl and —(C1-C4)alkylene-(5-10 membered heteroaryl) is optionally substituted with 1, 2, 3, or 4 substitutents independently selected from F, Cl, CN, N3, OH, (C1-C6)alkyl, (C1-C6)haloalkyl, and (C1-C6)alkoxy;
• and wherein the compound of Formula (I) is not one of the following compounds:
• the process comprising:
• contacting the compound of Formula (II):
• with a dichlorobenzene of Formula (III):
• to obtain a reaction mixture containing the compound of Formula (I);
• wherein the dichlorobenzene of Formula (III) is
