---|---|---|
A flask charged with dimethyl t-butoxycarbonyl-methylphosphonate (0.21 mL, 1.06 mmol) in 2 mL of dry THF/DMPU (10:1) was cooled to -780C where 0.52 mL of n-butyl lithium (2.5 M hexane solution, 32mmol) was added slowly via syringe. The reaction mixture was stirred at -780C for 10 minutes and then a solution of Compound 1 C (185 mg, 0.48 mmol) in 2 mL of dry THF was added. After warming to room temperature and an additional 20 minutes of stirring, the reaction was quenched with 5 mL of water and passed through a solid phase extraction column (SPE). The column was washed with EtOAc (50 mL) and the collected eluant was evaporated to give crude product which was purified by flash chromatography (EtOAc/Hexanes; gradient 15percent to 30percent) to give 205 mg (86percent) of Compound 1 D as a foamy white solid. MS (electrospray): mass calculated for C28H28F3NO4, 499.2; m/z found 500.2, [M+H]+. |
