Abstract

Novel pyrimido-(5,4b)(1,4)oxazine derivs., of formula (I), where R1 = H, 1-4C alkyl gp.; or phenyl gp.; R2: as in this case, a halogen atom, nitro gp., or 1-4C alkyl gp., are prepd. from cpds. of tautomeric formulae (IIa) and (IIb) and sulpho-chloride cpds. of general formula R2-SO2Cl (III), in the presence of a polar solvent and base. - Cpds. (I) are isolated and used as pharmaceutical intermediates.
