Reaction Steps

200 mg 4-chloro-2-[4-(4-chloro-phenyl)-piperazin-1-yl]-6,7-dihydro-thieno[3,2-d]pyrimidine 5-oxide (cf Example 124), 313.3 mg 5-aminomethyl-2-methyl-2H-pyrazol-3-ol and 359.25 μl diisopropylethylamine are placed in 4 ml dioxane, heated to 130° C. in the microwave for 0.3 hours and for a further 0.3 hours to 130° C. Then the reaction mixture is mixed with water. The precipitated substance is suction filtered and washed with water. The product is purified by semipreparative HPLC (method A). 130 mg of the product are obtained as a powder. Analytical HPLC-MS (method B): RT=1.61 min.
