Potassium Carbonate → HCID 178486054, compound

Participants

Reaction Steps

0.807 g potassium carbonate were added to a solution of 1.3 g cis-benzoic acid 4-(tert-butoxycarbonyl-methyl-amino)-cyclohexyl ester in 10 ml methanol. The reaction mixture was stirred at rt overnight. 2 ml sodium hydroxide solution (2M) were added and the mixture was stirred for 4 hours. After that time the mixture was diluted with EtOAc and washed with water and brine. The organic phase was passed through a hydrophobic frit and the solvent was evaporated. Purification was achieved by silica gel column chromatography (gradient: 100% i-hex.→100% methylene chloride→20:1 methylene chloride/methanol).
