The trisubstitutedpyrimidine 1 was identified through high-throughput screening as a novel calcium-sensing receptor (CaSR) antagonist. Small molecule CaSR antagonists and/or negative allosteric modulators have the potential to act as an anabolic agent for the treatment of osteoporosis. The investigation of structure−activity relationships around 1 resulted in the identification of 18c and 18d, which

mides via regioselective Suzuki coupling of 2,6-dichloronicotinamide with aryl boronic acids is described. Regioselectivity was achieved by chelation of the palladium(0) species to an ester/amide group. The air-stable palladium catalyst PXPd2, when used in reagent-grade methanol with K(2)CO(3) as the base, afforded the best regioselectivity and shortest reaction times among the catalysts screened.
