Versuchsvorschrift
Prepared in analogy to example 1 (b) from 2-morpholin-4-yl-5-nitro-benzoic acid (Example A27) and 1-(5-trifluoromethyl-[1,3,4]thiadiazol-2-yl)-piperazine trifluoroacetate (Example 62(b)). The crude material was purified by chromatography (SiO2, methanol/dichloromethane) to yield the title compound as a brown solid (yield 34%). MS (m/e): 473.4 (M+H+, 100%).
