Reaction Steps

1-[4′-(4-Bromo-3-methyl-isoxazol-5-yl)-biphenyl-4-yl]-cyclopropanecarboxylic acid ethyl ester (0.100 g, 0.243 mmol) was dissolved in THF (0.25M) and cooled to −78° C. n-Butyllithium (2.5M in hexanes, 0.1068 mL, 0.267 mmol) was slowly added and the reaction stirred for 30 minutes. 3,3-Dimethyl-4-phenyl-butyraldehyde (0.047 g, 0.254 mmol) was added and the reaction was stirred at −78° C. for 30 minutes then warmed to room temperature and continued stirring for 1 hour. The reaction mixture was submitted to standard aqueous workup to afford the title compound, which was used in the next step without further purification.
