Reaction Steps

5-(2-Methyl-pyrimidin-5-ylmethyl)-2-methylsulfanyl-1H-pyrimidin-4-one (50 mg, 0.20 mmol, 1 eq) and 5-(2-Amino-ethyl)-2-(5-trifluoromethyl-pyridin-2-yloxy)-benzonitrile (80 mg, 0.26 mmol, 1.3 eq) were heated at 130° C. (sealed bottle) in 500 μl of absolute ethanol for 24 hours. Solvent was then evaporated and the resulting crude was purified by chromatography on BIOTAGE SP1 purification device using 11 g normal phase silica KP—NH column and DCM/10% MEOH in DCM solvent system (gradient 10-80% of 10% MeOH in DCM in 20 column volumes). Solvent from the gathered fractions of appropriate composition was evaporated and the resulting oil was triturated with hexane to obtain 5-{2-[5-(2-methyl-pyrimidin-5-ylmethyl)-4-oxo-1,4-dihydro-pyrimidin-2-ylamino]-ethyl}-2-(5-trifluoromethyl-pyridin-2-yloxy)-benzonitrile (36 mg, yield=32.4%, purity=92%) in form of tain coloured powder.
