Abstract
A procedure for the preparation of morpholine compounds of the formula: ** (See formula) ** where R1 is hydrogen or C1-4alkyl, A is straight or branched C2-C4alkylene; B is -CH2-CH2, -, -CHCH-, (see formula), -CH2-O-, -CH2-S-, -S- U -O-; DE is CH-CH2- or C = CH- and C1 and C2 are each 1,2-phenylene optionally substituted with one or more substituents selected from the group consisting of halogen, C1-C4 alkyl, and C1-C4 alkoxy, and its non-toxic salts; whose procedure consists of submitting the morpholine compound of the formula: ** (See formula) ** where R8 is C1-C4 alkyl or arylalkyl (C1-C4), and R1, A, B, D-E-, C1 and C2 are as defined above, replacing the group R8 with hydrogen.
