A solution of the amine of Example 17 (0.90 g, 1.78 mmol), 1(S)-(4-benzyloxy-3-(methylsulfonamido)phenyl-1-triethylsiloxy-2-iodoethane (0.665 g, 1.60 mmol) and triethylamine (0.50 mL, 3.56 mmol) in THF (4 mL) was heated at 100° C. in a sealed tube for 60 h. The reaction mixture was cooled and evaporated in vacuo. The residue was flash chromatographed (silica gel; dichloromethane/ethyl ether/methanol: 25/25/0.75) to yield 0.740 g of the title compound as a white solid.
