ABSTRACT:
Compound of formula C is made by reacting a compound of formula A with an pyridyl boronic acid or pyridyl borate ester to form a compound of formula B; andcombining the compound of formula B with a pyridyl dihalide to form the compound of C;whereinR3, R4, R5, R6and R7are, independently at each occurrence, a C1-C20aliphatic radical, a C3-C20aromatic radical, or a C3-C20cycloaliphatic radical;X is, independently at each occurrence, CH or N;Y is chloro or bromo;Z is bromo or iodo; and when Y is bromo, Z is iodo;d, e, and g are, independently at each occurrence, an integer ranging from 0-4;f is an integer ranging from 0-2; andh is an integer ranging from 0-3.
