Versuchsvorschrift
5-(2,4-Bis-benzyloxy-5-chloro-phenyl)-4-bromo-isoxazole-3-carboxylic acid ethylamide (38 mg, 0.07 mmol) and 1-Methyl-4-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-piperazine (31 mg, 2 equiv.) were coupled together using the suzuki method previously described to provide 37 mg (83% yield) of the crude as a brown oil which was taken on to the deprotection step.
