摘要:
A process for preparing an imidazo [4,5-c] pyridine compound of formula (II): ** Formula ** in which: - R1 is selected from phenyl substituted with 0-3 R6; 5- or 6-membered heterocyclic ring containing 1-3 heteroatoms selected from the group of O, N, and S, substituted with 0-2 R6; 1-naphthyl substituted with 0-3 R6; 2- naphthyl substituted with 0-3 R6; C3-7 cycloalkyl; C5-7 cycloalkenyl; - R2, R4 and R5 are independently selected from hydrogen; linear or branched C1-6 alkoxy; C1-6 linear or branched alkyl; F; Cl; Br; I; OH; CN; NO2; NR7R8; OCF3; CF3; C (>; = O) R9; phenyl; phenoxy; benzyl; hydroxymethyl; - X is selected from the group -CH2-; -CH (CH3) -; -CH2-CH2-; -CH2-CH2-CH2-; -CH2-CH2-CH2-CH2; -OCH2-CH2-; -SCH2-CH2-; -NR10 -CH2-CH2-; C3-7 cycloalkylidene; -C (CH3) 2; -CH2-CH (CH3) -CH2-; -CH (CH3) -CH2-CH2-; -CH2- CH2-CH (CH3) -; -CH>; = CH-CH2-; - R3 is selected from phenyl substituted with 0-3 R17; aromatic 5- or 6-membered heterocyclic ring containing 1-3 heteroatoms selected from the group of O, N, and S, substituted with 0-2 R17; 1-naphthyl substituted with 0-3 R17; 2-naphthyl substituted with 0-3 R17; C3-7 cycloalkyl; C4-10 cycloalkenyl with the proviso that the double bond cannot be adjacent to a nitrogen; - R6 and R17 are independently selected from H; linear or branched C1-6 alkoxy; C1-6 linear or branched alkyl; F; Cl; Br; I; OH; CN; NO2; NR13R14; OCF3; CF3; C (>; = O) R18; phenyl; phenoxy; benzyl; hydroxymethyl; - R7 and R8 are independently selected from H; C1-6 linear or branched alkyl; phenyl; C (>; = O) R12 or R7 and R8, together with the nitrogen to which they are attached, combine to form a 5-6 member ring; - R9 and R18 are independently selected from H; OH; C1-6 linear or branched alkyl; linear or branched C1-6 alkoxy; NR15R16; phenyl; - R10 is selected from the group H; C1-6 linear or branched alkyl; phenyl; - R12 is selected from the group H; C1-6 linear or branched alkyl; phenyl; - R13 and R14 are independently selected from H; C1-6
