A process for preparing a compound of Formula I: or a salt thereof, comprising: (a) treating a compound of Formula 13: or a salt thereof with a compound of Formula 14: or a salt thereof, to form a compound of Formula I; and optionally forming a salt of the compound of Formula 1; (b) preparing the compound of Formula 13 by treating a compound of Formula 12: or a salt thereof, with a compound having the formula: XC Z, to form a compound of Formula 13 or a salt thereof, and (c) preparing the compound of Formula 12 by treating a compound of Formula 11: or a salt thereof, with a nitro reduction system to form a compound of Formula 12 or salt thereof; wherein the nitro reduction system comprises: (i) palladium, platinum, rhodium, ruthenium, nickel, copper, iron, or tin; (ii) LiAlH 4, NaBH 4, or diisobutylaluminium hydride (DIBAL); or (iii) an organic compound capable of providing hydrogen; wherein X is halogen, C 1 -C 6 alkoxy, or C 6 -C 10 aryloxy, each optionally substituted with one or more substituents independently selected from the group consisting of Ci-C 6 alkyl, C 1 -C 6 haloalkyl, halogen, CN, OH, C 1 -C 6 alkoxy, and NR 1 R 2, where R 1 and R 2 are each independently selected from hydrogen and C 1 -C 6 alkyl; and wherein Z is a leaving group selected from halogen, C 1 -C 6 alkoxy, C 6 -C 10 aryloxy and a 5-membered heteroaryl containing at least one nitrogen directly bonded to the C=O of XC Z, each optionally substituted with one or more substituents independently selected from the group consisting of C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, halogen, CN, OH, C 1 -C 6 alkoxy, and NR 5 R 6 where R 5 and R 6 are each independently selected from hydrogen and C 1 -C 6 alkyl; provided that if Z is optionally substituted C 1 -C 6 alkoxy, optionally substituted C 6 -C 10 aryloxy, then Z and X are the same. (a) treating a compound of Formula 13: or a salt thereof with a compound of Formula 14: or a salt thereof, to form a compound of Formula I; and optionally forming a salt of the compound of Formula 1; (b) preparing the compound of Formula 13 by treating a compound of Formula 12: or a salt thereof, with a compound having the formula: XC Z, to form a compound of Formula 13 or a salt thereof, and (c) preparing the compound of Formula 12 by treating a compound of Formula 11: or a salt thereof, with a nitro reduction system to form a compound of Formula 12 or salt thereof; wherein the nitro reduction system comprises: (i) palladium, platinum, rhodium, ruthenium, nickel, copper, iron, or tin; (ii) LiAlH 4, NaBH 4, or diisobutylaluminium hydride (DIBAL); or (iii) an organic compound capable of providing hydrogen; (i) palladium, platinum, rhodium, ruthenium, nickel, copper, iron, or tin; (ii) LiAlH 4, NaBH 4, or diisobutylaluminium hydride (DIBAL); or (iii) an organic compound capable of providing hydrogen; wherein X is halogen, C 1 -C 6 alkoxy, or C 6 -C 10 aryloxy, each optionally substituted with one or more substituents independently selected from the group consisting of Ci-C 6 alkyl, C 1 -C 6 haloalkyl, halogen, CN, OH, C 1 -C 6 alkoxy, and NR 1 R 2, where R 1 and R 2 are each independently selected from hydrogen and C 1 -C 6 alkyl; and wherein Z is a leaving group selected from halogen, C 1 -C 6 alkoxy, C 6 -C 10 aryloxy and a 5-membered heteroaryl containing at least one nitrogen directly bonded to the C=O of XC Z, each optionally substituted with one or more substituents independently selected from the group consisting of C 1 -C 6 alkyl, C 1 -C 6 haloalkyl, halogen, CN, OH, C 1 -C 6 alkoxy, and NR 5 R 6 where R 5 and R 6 are each independently selected from hydrogen and C 1 -C 6 alkyl; provided that if Z is optionally substituted C 1 -C 6 alkoxy, optionally substituted C 6 -C 10 aryloxy, then Z and X are the same.
