Participants

Reaction Steps

A solution of (2-{3-chloro-5-[(2-cyano-ethyl)-isobutyl-carbamoyl]-phenoxy}ethyl)-pyridin-4-yl-carbamic acid tert-butyl ester (0.059 g) in a mixture of dichloromethane (5 ml) and trifluoroacetic acid (2 ml) was stored at room temperature for 18 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.047 g) was obtained as a colourless oil by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure.
