H-PRO-NME2

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In 86 ml of ethanol was dissolved 4.3 g of compound (88) and after adding thereto 210 mg of 10% palladium-carbon, the mixture was stirred vigorously for 90 minutes in a hydrogen stream. After filtering off the catalyst, ethanol was distilled off under reduced pressure to provide 2.19 g of crude (S)-N,N-dimethyl-2-pyrrolidinecarboxamide (89). after adding After filtering off the catalyst, ethanol was distilled off under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In analogy to example 22.3, (4-{2-[2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazin-1-yl)-acetic acid (example 22.2) was coupled with H-Pro-NMe2, using general method C, to give (S)-1-[2-(4-{2-[2-(4-chloro-benzoylamino)-thiazol-4-yl]-acetyl}-piperazin-1-yl)-acetyl]-pyrrolidine-2-carboxylic acid dimethylamide. Off-white solid. MS 547.5 ([M+H]+)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of (S)-2-(N,N-dimethylcarbamoyl)pyrrolidine (426 mg, 3 mmol), (Chem. pharm. Bull. 1973, 21, 2112-2116), 3-bromo-1-propanol (0.41 ml, 4.5 mmol) and potassium carbonate (829 mg, 6 mmol) in acetonitrile (6 ml) was heated at reflux for 8 hours. The mixture was allowed to cool and was partitioned between methylene chloride and water. The organic layer was separated, washed with brine, dried (MgSO4) and the solvent removed by evaporation. The residue was purified by column chromatography, eluting with methylene chloride/methanol (a gradient from 90/10 to 60/40) to give (S)-1-(3-hydroxypropyl)-2-(N,N-dimethylcarbamoyl)pyrrolidine (290 mg, 48%). was heated at reflux for 8 hours to cool was partitioned between methylene chloride and water The organic layer was separated washed with brine dried (MgSO4) the solvent removed by evaporation The residue was purified by column chromatography eluting with methylene chloride/methanol (a gradient from 90/10 to 60/40)
