Abstract
Abstract Treatment of 4-hydroxyisoxazolo [5.4-d] pyrimidines (II) with phosphorous oxychloride furnishes the 4-chloro analogues (III) which react readily with ammonia, primary and secondary amines yielding the corresponding 4-amino, 4-mono and 4-disubstituted amino derivatives (IV) respectively.
