Procedure
To a solution of 0.25 mmol 2-morpholin-4-yl-5-nitro-benzoic acid (Example 2.1) in 0.7 ml dimethylformamide 0.26 mmol TBTU, 1.6 mmol N-ethyldiisopropylamine and 0.25 mmol 6-chloro-2-piperazin-1-yl-benzothiazole were successively added. The reaction was then stirred at RT for two hours, concentrated in vacuo and treated with 5 ml water. The solid is filtered off and recrystallized form methanol to yield the title compound as a yellow solid.
