Reaction Steps

To a solution of 4-{(S)-2-[4-(4-chloro-phenyoxy)-phenoxymethyl]-pyrrolidin-1-yl}-4-oxo-butyric acid (d4) (500 mg, 1.2 mmol, 1 eq.) in a mixture of methanol (6 ml) and benzene (5 ml) was added dropwise TMSCHN2 (2 M in hexane, 3 ml, 6 mmol, 3 eq.) with stirring. The mixture was stirred until the starting acid was consumed by indication of yellow color persists). Then volatile material was removed under reduced pressure.
