Reaction Steps

A mixture of Intermediate 40 (0.30 g, 0.90 mmol) and Intermediate 4 (375 mg, 1.1 mmol) in DMF (5 mL) was treated with N,N-diisopropylethylamine (0.47 mL, 2.7 mmol) and catalytic tetra-n-butylammonium iodide (100 mg). The mixture was heated for 3 days in a 55° C. oil bath. The mixture was concentrated under reduced pressure and purified via automated flash silica gel chromatography, using a 12 g Silicycle SiliSep flash column (dichloromethane/methanol/ammonium hydroxide). Concentration of the desired fractions under reduced pressure provided the title compound. ES/MS calcd. for C31H39F3N3O4Si+ 602.3. Found m/z=602.4 (M+H)+.
