Reaction Steps

In analogy to the procedure described in example 8, the 6-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-methyl-5-nitro-3H-pyrimidin-4-one (example 7) was treated with tert.-butyl-(4-chlorobutoxy)dimethylsilane and potassium carbonate in N,N-dimethyl-formamide at 80° C. to yield the 4-[4-(tert-butyl-dimethyl-silanyloxy)-butoxy]-6-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-methyl-5-nitro-pyrimidine as a yellowish oil; MS: [M+H]+=519; and the 3-[4-(tert-butyl-dimethyl-silanyloxy)-butyl]-6-[4-(4-fluoro-phenyl)-piperidin-1-yl]-2-methyl-5-nitro-3H-pyrimidin-4 one as a yellowish oil; MS: [M+H]+=519.
