Using a procedure analogous to that used to prepare 6D, 59C (2.46 g, 4.8 mmol) was reacted with 5,5′,5′-tetramethyl-[2,2′]bi[[1,3,2]dioxaborinanyl] to give 59D (560 mg, 22%) as a solid. 1H NMR (400 MHz, MeOD-d4) δ ppm 1.25-1.41 (m, J=4.39 Hz, 3 H) 2.27 (s, 3 H) 2.61 (s, 2 H) 2.92 (s, 2 H) 4.22 (s, 2 H) 4.64 (s, 1 H) 6.84-7.56 (m, 12 H).
