Методика

To a solution of 2-phenyl-1,3-thiazole-4-carboxylic acid (5.1 mg) and DIPEA (3 eq) in DMF (0.4 mL) was added TBTU (1.2 eq) in DMF (0.2 mL). Then, a solution of 4-(2-amino-acetyl)-piperazine-1-carboxylic acid ethyl ester (5.4 mg, prepared as described in WO2006114774) in DMF (0.2 mL) was added. After stirring overnight at RT, the reaction mixture was directly purified by preparative HPLC (IV) to give 4.9 mg of the desired product.
