(1R)-2-(1H-indol-3-yl)-1-(4-phenyl-1H-imidazol-2-yl)ethanamine (2 g; 0.0066 mol; prepared according to experimental conditions analogous to the preceding examples and using the appropriate starting compounds and reaction products) was diluted in 10 ml n-butanol. 2-bromopyrimidine (1 g; 0.0066 mol) and then diisoethylamine (1.15 ml; 0.0066 mol) were added dropwise. The mixture was then heated to around 80° C. for about 16 hours. The n-butanol was evaporated and the residue taken up in water and ethyl acetate. The organic phase was washed with water and then with a saturated solution of sodium chloride before being dried over magnesium sulfate and concentrated using a rotative evaporator. After purification over a silica column (eluent: ethyl acetate-heptane/7-3, followed by CH2Cl2-MeOH-NH4OH/95-4.5-0.5 and ethyl acetate). A white powder was obtained (yield of 20%). Free base. Melting point: 138-140° C. MH+=381.2.
