Participants

Reaction Steps

A solution of 4-chloro-6-pyridin-3-yl-2-pyridin-2-yl-pyrimidine (Intermediate A) (1 eq, 0.2 g), C-(1H-indol-4-yl)-methylamine (1.1 eq, 0.12 g) and K2CO3 (3 eq, 0.308 g) in NMP (6 ml) is heated using microwave radiation at 120° C. for 1 hour. After cooling to room temperature, the mixture is partitioned between EtOAc/water and the organic portion is separated, washed with brine, dried (MgSO4) and concentrated in vacuo. The crude residue is purified by mass directed preparative HPLC eluting with acetonitrile in water—0.1% TFA and the appropriate fractions are combined and concentrated in vacuo. The resulting residue is loaded onto a SCX-2 cartridge eluting with MeOH followed by 2M NH3 in MeOH. The methanolic ammonia fractions are concentrated in vacuo and dried under vacuum to afford the title compound [M+H]+=379.
