実験手順
Prepared in analogy to Example 1 from 5-methanesulfonyl-2-((S)-2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid (Example A2(c)) and azetin-3-ol. The crude material was purified by flash chromatography (ethyl acetate/n-heptane) to yield the title compound as a white crystalline solid (yield 43%). MS (m/e): 367.9 (M+H+, 100%).
