A process for preparing a compound of Formula I: ** (See formula) ** or a salt thereof, comprising: (a) treating an isolated compound of Formula 13: ** (See formula) ** or a salt of this with a compound of Formula 14: ** (See formula) ** or a salt thereof to form a compound of Formula (I); and (b) optionally forming a salt of the compound of Formula (I); wherein X is halogen, C1-C6 alkoxy, C6-C10 aryloxy, or a 5-membered heteroaryl containing at least one nitrogen directly attached to C = O of the compound of Formula 13, each optionally substituted with one or more independently selected substituents from the group consisting of C1-C6 alkyl, C1-C6 haloalkyl, halogen, CN, OH, C1-C6 alkoxy and NR1R2, where R1 and R2 are each independently selected from hydrogen and C1-C6 alkyl. |
