Reaction Conditions

Reaction Steps

2-Fluoropyridine-3-boronic acid (63.9 mg), tetrakis(triphenylphosphine)palladium (26.2 mg) and a 1 N sodium carbonate solution (453 μl) were added to a solution of (±)-N,N-di(tert-butyloxycarbonyl)-[(4aR*,6R*,8aS*)-8a-(5-bromo-2-fluorophenyl)-6-trifluoromethyl-4,4a,5,6,8,8a-hexahydro-7-oxa-3-thia-1-azanaphthalen-2-yl]amine (138 mg) in DMF (9.9 ml), and the mixture was stirred in a nitrogen atmosphere at 85° C. for seven hours. The reaction solution was cooled to room temperature and then diluted with ethyl acetate. The organic layer was washed with water and brine. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. Dichloromethane (4.0 ml) and TFA (1.0 ml) were added to the residue, and the mixture was stirred at room temperature for four hours. When the reaction was completed, the reaction solution was diluted with dichloromethane and ice was added, followed by neutralization with a sodium bicarbonate solution. The aqueous layer was extracted with chloroform, and the organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by NH-silica gel column chromatography. The resulting white solid was washed with diethyl ether to obtain the title compound (14.0 mg).
