Procedure
Prepared according to the method described in Example 15g) from toluene (4 ml), 2M aqueous sodium carbonate (0.5 ml), (1S,2R)-4-[2-(tert-butyldimethylsilanyloxy)-1-methyl-4-pyridin-3-yl-butoxy]benzeneboronic acid (0.200 g, Example 15f)), ethanol (1 ml), 6-bromo-2-N,N-dimethylaminopyridine (0.201 g, Example 18a)) and tetrakis(triphenylphosphine)palladium(0) (0.020 g) with heating at 120° C. for 4 hours. The product was purified by normal-phase HPLC eluting with a gradient of 0-25% ethanol in dichloromethane to give the title compound as an oil (0.091 g).
