Abstract:
A method of making a compound of Formula Ia whereineach R3 is independently hydrogen or C1-C6alkyl; A is X is O or S; n is 0 to 6; each Rb is independently hydrogen, â€”CF3, â€”OC1-C6alkyl, halo, â€”SH, â€”SC1-C6alkyl, phenyl, or â€”C1-C6alkyl; B is hydrogen, each R is independently hydrogen or C1-C6alkyl; each Y is independently phenyl, substituted phenyl, pyridyl or substituted pyridyl, wherein any substituents are independently selected from â€”CF3, halo, â€”OC1-C6alkyl, or â€”C1-C6alkyl; and m is 0 to 5; the method comprising the steps of: with H2Nâ€”B to form a compound of Formula Ia.
