実験手順
The compound of the general formula (II) can be produced, for example, as follows. A 2-nitrophenylacetonitrile derivative is reacted with a 2-halogeno- or alkylsulfonyl-4,6-dimethoxypyrimidine in the presence of a base, or a 2-halogeno-nitrobenzene derivative is reacted with 2-(4,6-dimethoxypyrimidine-2-yl)acetonitrile in the presence of a base, to obtain 2-(4,6-dimethoxypyrimidine-2-yl)-2-(2-nitrophenyl)acetonitrile (IV). The compound (IV) is subjected to oxidative decyanation to obtain a compound of the general formula (V). The nitro group of the compound (V) is reduced to convert it into an amino group to obtain a compound of the general formula (VI). The carbonyl group of the compound (VI) is reduced to a hydroxymethyl group to obtain a compound of the general formula (II).
