The reaction mixture was heated to 90° C. for 4 hours in a sealed tube. On cooling to room temperature a the solid formed was collected by filtration to yield 3.0 g 2-(4-methylphenyl)-5-hydroxymethyl-imidazole which was converted according to the procedure described in Example VII to yield 2-(4-methylphenyl-4(5)-[(4-(2-pyrimidinyl)-piperazin-1-yl)-methyl]-imidazole (Compound 133), m.p. 178-180° C.
