Reaction Steps

4-Methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoic acid (1.3 g), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (1.44 g) and 3H-[1,2,3] 1-hydroxy-7-azabenzotriazole (0.077 g) was added to a stirred solution of ethylamine in tetrahydrofuran (2M, 5 ml) in chloroform (30 ml) and the mixture was stirred for 24 h. The mixture was poured into water, passed through a hydrophobic filter tube and the organic phase was concentrated under vacuum. The residual solid was purified on an SCX cartridge eluting with methanol to give the title compound as a pale yellow solid (1.36 g).
