Abstract
Improvements introduced in the object of the main patent No. 402,400 filed on May 5, 1972, for: "Procedure for the preparation of new derivatives of substituted tetrahydro-m-oxazines", according to which when said derivatives respond to the following general formula: ** (See formula) ** where Ar is a phenyl nucleus substituted with one or two halogen atoms chosen from chlorine and fluorine, or with one or two alcohol radicals comprising a maximum of four carbon atoms, or with one or two methoxy groups, or with a radical chosen from among the following: trifluoromethyl, benzyloxy, and methylcarbonylamino; These improvements consist of condensing an amino alcohol of formula (II): Ar - 0 - CH2 - CHOH - CH2 - CH2 - NH2 (II) with thiophosgene of formula (III): CS CL2 (III) to give a hydroxylated isothiocyanate of formula (IV): Ar - O - CH2 - CHOH - CH2 - CH2 - N = C = S (IV) which then cyclizes; Ar in formulas (II) and (IV) having the same meaning as in formula (I).
