実験手順

To a mixture of (R)-1-(4-cyclopropyl-benzenesulfonyl)-piperazine-2-carboxylic acid 4-trifluoromethoxy-benzylamide (39 mg) obtained in Example 1100, Step 4 and 2,7-dichloro-5-cyclopropyl-thiazolo [4,5-d]pyrimidine (20 mg) in chloroform (1.0 ml) was added N,N-diisopropylethylamine (20 μl) at room temperature. After stirring overnight at room temperature, the reaction mixture was diluted with ethyl acetate, and the mixture was partitioned by adding water. The organic layer was dried over anhydrous sodium sulfate, filtrated, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:1) to give the title compound (54 mg).
