Procedure
is obtained analogously to the procedure described in example 25 a) from 3-methoxy-1,2-diaminobenzene and 4-methyl-3-thienyl isothiocyanate in anhydrous THF, followed by medium-pressure chromatography on silica gel using a mixture of 1 part of toluene and 1 part of ethyl acetate. Crystalline solid, m.p.: 148-153° C. Solidification of the melt and next m.p. at 260° C.
Workup
- customis obtained analogously to the procedure
- customat 260° C.
