Vorschrift

EtOAc (6 ml) was added to (5R)-5-(4-{[(2-Fluorophenyl)methyl]oxy}phenyl)-L-prolinamide (E1, 300 mg) and this was heated at 60° C. for an hour to dissolve the compound. Then methanesulfonic acid (65 μl, 1.05 eq) was added to the solution and as soon as the acid was added, the solution went cloudy. This was then left to temperature cycle (0-40° C.) for 2 days. The compound was isolated by filtration as a white solid, washed with EtOAc and dried in vacuo at 40° C. overweek-end to afford 335 mg of the title compound.
