Abstract

4-(N-[2-Amino-4-hydroxy-6-pteridyl)-methyl]-amino)-3-bromobenzenearsonic Acid (VII).- Using the general procedure 115 g. of 3-bromoarsanilic acid, 200 g. of I and 225 g. of I1 gave 300 g. of crude product. The crude product was dissolved in 18 1. of a 0.1 N sodium hydroxide solution at 75'and treated with calcium chloride and zinc chloride as described for compound V. The filtrate was adjusted to pH 2.0 and cooled; yield 22.0 g. The product was ...
