A. Iodination of Diol 6 to Prepare 7a [0228] Triphenylphospine (257.2 g) and imidazole (66.7 g) were charged to a reactor. DCM (490 mL) was charged, agitation was initiated and the solution was cooled to 0 C. Iodine (249.2 g) was added as a solid portion-wise over 1 h while maintaining the internal temperature below 10 C. Upon completion of the addition, a solution of 6 (50 g) in DCM (113 mL) was slowly charged to the reactor over 0.5 h while maintaining the internal temperature below 10 C. After stirring for 2.5 h, an aqueous solution of NaCl (25 g) in water (225 mL) was charged to the reactor. Following phase separation, the bottom organic layer was diluted with n-heptane (550 mL). The organic phase was washed with an aqueous solution of sodium sulfite (21 g) in water (190 mL). Following layer separation, the organic phase was concentrated to 600 mL via vacuum distillation. Additional n-heptane (550 mL) was charged, and the mixture was again concentrated to 600 mL via vacuum distillation. The resulting slurry was filtered over a silica gel plug (85 g) that had been slurry packed with n-heptane. The silica gel plug was rinsed with additional n-heptane (1 L), and the filtrate was then concentrated via vacuum distillation to provide the desired product 7a as a colorless liquid (114 g, 70%). 1H NMR (400 MHz, CDCl3) delta 3.33 (s, 2H), 0.95 (s, 2H). 13C NMR (75 MHz, CDCl3): 19.1, 22.7, 26.0.
