Reaction Steps

81.3 mg (0.9 mmol) of phenol and 325.5 mg (2.4 mmol) of K2CO3 were added to 400.0 mg (0.78 mmol) of 1-(4-{4-[2-tert-butyl-6-(trifluoromethyl)pyrimidin-4-yl]piperazin-1-yl}butyl)-5-methyl-2-oxo-1,2-dihydropyrimidin-4-yl thiocyanate from Example 7.1 in 40 ml of acetonitrile and 500.0 mg of molecular sieves (3 Å). The reaction mixture was then stirred at room temperature for 12 hours. Insolubles were filtered off, methylene chloride was added to the filtrate, followed by extraction with aqueous brine. The residue after drying of the organic phase, removal of the desiccant by filtration and evaporation of the solvent in vacuo was taken up in 100 ml of diisopropyl ether and heated. The precipitate was filtered off with suction and the mother liquor was concentrated somewhat. The mother liquor was then mixed with pentane and cooled in an ice bath. The precipitated solid was filtered off with suction, washed and dried in vacuo at 40° C., resulting in 120 mg of the title compound.
