Versuchsvorschrift

A solution of 4-amino-cyclopentane-1,2-diol; compound with trifluoroacetic acid (745 mg, 3.23 mmol) in DMF (15 ml) was treated with DIPEA (1.12 ml, 6.4 mmol) and the mixture was stirred for 5 minutes at room temperature. Then (R)-2-[(Morpholine-4-carbonyl)-amino]-3-phenylmethanesulfonyl-propionic acid (1.15 g, 3.23 mmol) was added followed by HATU (1.23 g, 3.24 mmol). This mixture was stirred at room temperature overnight and then evaporated. The residue was subjected to flash chromatography on silica eluting with ethyl acetate and then with a mixture of ethyl acetate and methanol to give morpholine-4-carboxylic acid [(R)-1-(3,4-dihydroxy-cyclopentylcarbamoyl)-2-phenylmethanesulfonyl-ethyl]-amide as a brown solid (680 mg). LC/MS: RT=2.64 min. (215 and 254 nM), MH+=456.
