PROCEDURE

实验过程

Prepared according to the procedure described in Example 110, Step 3, using 2-benzyloxy-1-[5-(4-bromo-phenyl)-3-methyl-isoxazol-4-yl]ethanol and (cis)-2-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-cyclopropanecarboxylic acid ethyl ester. After the reaction the crude material was dissolved in EtOH (3 mL) and purified via preparatory chiral HPLC (Chiralcel-AD column, 8% EtOH in hexanes, 70 minutes) to afford three separate compounds. The first compound off of the column, containing a mixture of cis-cyclopropyl diastereomers, was the title compound.
