실험 절차

Prepared according to the method described in Example 12b) from (1S,2R)-4-[2-(tert-butyldimethylsilanyloxy)-1-methyl-4-pyridin-3-ylbutoxy]benzeneboronic acid (0.20 g, Example 11)), 4-chloro-iodobenzene (0.24 g), 2M aqueous sodium carbonate (0.5 ml) and tetrakis(triphenylphosphine)palladium (0) (0.1 g) in toluene (4 ml) and ethanol (1 ml). The reaction mixture was heated at 100° C. for 4 hours. After cooling, the solution was concentrated under reduced pressure. Concentrated hydrochloric acid (1 ml) was added to a solution of the residue in methanol (5 ml) and the suspension was stirred at room temperature for 3 hours. After work up, the residue was purified by normal-phase HPLC eluting with a gradient of 0-25% ethanol in dichloromethane to give a gum, from which the oxalate salt was made (0.11 g).
