Versuchsvorschrift

5-(3-methanesulfonyloxy-propyl)-3-methyl-1H-pyrrole-2,4-dicarboxylic acid 2-tert-butyl ester 4-ethyl ester 1g (1.13 g, 2.9 mmol) was dissolved in 5.6 ml of dichloromethane under stirring, and 1-amino-3-morpholin-4-yl-propan-2-ol 53c (0.93 g, 5.8 mmol) was added to the solution at room temperature. Upon completion of the addition, the reaction mixture was stirred at room temperature overnight and heated for 14 hours at 45° C. in an oil bath. After thin lay chromatography showed the disappearance of starting materials, the reaction mixture was added with saturated brine (15 ml), exacted with dichloromethane (20 ml×3). The combined organic extracts were concentrated under reduced pressure, purified by silica gel column chromatography to obtain the title compound 5-[3-(2-hydroxy-3-morpholin-4-yl-propylamino)-propyl]-3-methyl-1H-pyrrole-2,4-dicarboxylic acid 2-tert-butyl ester 4-ethyl ester 53d (600 mg, yield 72.5%) as a colorless oil.
