Abstract

1,226,251. 1,3 - Dialkylxanthines and substituted uracils. KRAKOWSKIE ZAKLADY FARMACEUTYCZNE POLFA PRZEDSIEBIORSTWO PANSTWOWE. 15 Jan., 1969 [30 Jan., 1968], No. 2409/69. Heading C2C. Compounds of formula in which R 1 and R 2 are allyl and R 3 and R 4 are each H, alkyl or hydroxyalkyl or are linked together with the N to form a heterocyclic ring, are prepared by cyclization of the novel compounds of a formula which are prepared by reaction of an amine H.N.R 3 R 4 with a compound of a formula which may be prepared as in Specification 1,212,334.
