The compound according to claim 1, wherein: G.sub.1 is hydrogen; G.sub.2 is halo or isopropyl, wherein said isopropyl is optionally substituted with up to 3 substituents independently selected from R'; and G.sub.3 is an isopropyl or a C3-C10 cycloaliphatic ring, wherein said G.sub.3 is optionally substituted with up to 3 substituents independently selected from R'. 3. The compound according to claim 2, wherein: G.sub.1 is hydrogen; G.sub.2 is halo; and G.sub.3 is a C3-C10 cycloaliphatic ring, wherein said G.sub.3 is optionally substituted with up to 3 substituents independently selected from methyl, ethyl, propyl, or butyl. 4. The compound according to claim 1, wherein: G.sub.1 is hydrogen; G.sub.2 is CN, halo, or CF.sub.3; and G.sub.3 is an isopropyl or a C3-C10 cycloaliphatic ring, wherein said G.sub.3 is optionally substituted with up to 3 substituents independently selected from R'. 5.
