Product 1

HCID 58673082(3-Hydroxy-azetidin-1-yl)-[5-methanesulfonyl-2-((R)-2,2,2-trifluoro-1-methyl-ethoxy)-phenyl]-methanoneYield 30%

Procedure

Prepared in analogy to Example 1 from 5-methanesulfonyl-2-((R)-2,2,2-trifluoro-1-methyl-ethoxy)-benzoic acid (Example A3(b)) 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 30%). MS (m/e): 368.0 (M+H+, 100%).
