HCID 66578863(cis)-2-[4'-(3-Methyl-4-phenethylsulfanylmethyl-isoxazol-5-yl)-biphenyl-4-yl]-cyclopropanecarboxylic acid ethyl ester

Procedure

Prepared according to the procedure described in Example 3, Step 5, using 5-(4-bromo-phenyl)-3-methyl-4-phenethylsulfanylmethyl-isoxazole and (cis)-2-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-cyclopropanecarboxylic acid ethyl ester. After the reaction the material was purified using chiral preparatory HPLC (Chiralcel AS column, 5% EtOH in hexanes, 42 minute run). The first enantiomer to come off of the column is Enantiomer A.
