1. A method of synthesizing compounds represented as Formula I: wherein n has the value of 0 or 1, and Cy is a heteroaryl group chosen from the group of 2-furanyl, 3-furanyl, 2-oxazolyl, 4-oxazolyl, 5-oxazolyl, 3-isoxazolyl, 4-isoxazolyl, 5-isoxazolyl, 1,3,4-oxadiazol-2-yl, 1,2,4-oxadiazol-3-yl, 1,2,4-oxadiazol-5-yl, 2-thiazolyl, 4-thiazolyl, 5-thiazolyl, 3-isothiazolyl, 4-isothiazolyl, 5-isothiazolyl, 1,3,4-thiadiazol-2-yl, 1,2,4-thiadiazol-3-yl, 1,2,4-thiadiazol-5-yl and 4-pyridinyl, which heteroaryl groups are optionally substituted with up to three non-hydrogen substituents independently selected from C1-6 alkyl, substituted C1-6 alkyl, C2-6 alkenyl, substituted C2-6 alkenyl, C2-6 alkynyl, substituted C2-6 alkynyl, C3-8 heterocyclyl, substituted C3-8 heterocyclyl, C3-8 cycloalkyl, substituted C3-8 cycloalkyl, C5-10 aryl, C5-10 heteroaryl, substituted C5-10 aryl, substituted C5-10 heteroaryl, C1-6 alkyl-C5-10 aryl, C1-6 alkyl-C5-10 heteroaryl, substituted C1-6 alkyl-C5-10 aryl, substituted C1-6 alkyl-C5-10 heteroaryl, C5-10 aryl-C16 alkyl, C5-10 heteroaryl-C1-6 alkyl, substituted C5-10 aryl-C1-6 alkyl, substituted C5-10 heteroaryl-C1-6 alkyl, halo, —OR′, —NR′R″, —CF3, —CN, —NO2, —C2R′, —SR′, —N3, —C(═O)NR′R″, —NR′C(═O)R″, —C(═O)R′, —C(═O)OR′, —OC(═O)R′, —OC(═O)NR′R″, —NR′C(═O)OR″, —SO2R′, —SO2NR′R″, and —NR′SO2R″, where R′ and R″ are independently selected from hydrogen, C1-6 alkyl, C3-8 cycloalkyl, C3-8 heterocyclyl, C5-10 aryl, C5-10 heteroaryl or C5-10 aryl-C1-6 alkyl, or R′ and R″ and the atoms to which they are attached together can form a C3-8 heterocyclic ring, wherein the term “substituted”, as applied to alkyl, alkenyl, alkynyl, heterocyclyl, cycloalkyl, aryl, heteroaryl, alkylaryl, alkylheteroaryl, arylalkyl and heteroarylalkyl, refers to substitution by one or more alkyl, aryl, heteroaryl, halo, —OR′ and —NR′R″ groups, or pharmaceutically acceptable salts thereof, comprising coupling a mono-protected diazabicycle in which one of the two amine functional groups is rendered un-reactive by suitable derivatization with a suitably functionalized heteroaryl acid chloride or other reactive carboxylic acid derivative. |
