Taylor synthesis

The synthesis of 2-alkoxymethylpteridines (antiallergic compounds) has also been achieved by the Taylor synthesis <1996EJM273> (Scheme 31). The 3-aminopyrazine-2-carboxamide 163 reacted with orthoesters to give 2-alkoxymethylpteridine derivative 164. Alternatively, 164 was synthesized by condensing 3-aminopyrazine-2-car-bonitrile 165 with the acetoxyamidine 166 followed by the base hydrolysis (Table 9). [Pg.945]
