Versuchsvorschrift
From 7-oxo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-sulfonyl chloride (the compound of Preparation Example 7) (285 mg) and (1S)-1-(4-fluorophenyl)-2-(methylamino)ethanol (the compound of Preparation Example 38) (230 mg), the title compound (370 mg) was obtained as a light brown solid, in the same way as Preparation Example 41. The NMR data matched the racemic mixture described in Preparation Example 48. The optical purity as measured by high performance liquid chromatography (ChiralPak AD-H, hexane:2-propanol=8:2) was >99% e.e.
