1-ISOBUTYL-4-(4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLAN-2-YL)-1H-PYRAZOLE Chemical Properties,Usage,Production

Uses

1-Isobutylpyrazole-4-boronic acid, pinacol ester

Uses

1-Isobutylpyrazole-4-boronic acid pinacol ester can be used:

In the synthesis of 7-azaindole derivatives as potent PDK1 inhibitors.
As a reactant in the synthesis of imidazo[1,2-a]pyrazine derivatives as potent phosphodiesterase 10A inhibitors.
To prepare 2-substituted-3-aroyl-benzo[b]furan derivatives.

Synthesis

269410-08-4

78-77-3

827614-66-4

To 4-pyrazoleboronic acid pinacol ester (1 g, 5.15 mmol, 1.00 eq.) and isobutyl bromide (1.05 g, 7.66 mmol, 1.49 eq.) in ethyl acetate (60 mL), Cs2CO3 (3.36 g, 10.31 mmol, 2.00 eq.) was added. The reaction mixture was stirred at 80 °C for 4 hours. After completion of the reaction, it was cooled to room temperature and filtered to remove insoluble solids. The filtrate was diluted with ethyl acetate (30 mL) and subsequently washed with brine (40 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated in vacuum to afford 1-isobutyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (1.14 g, 88% yield) as a colorless oil.1H-NMR (300 MHz, CDCl3): δ 7.78 (s, 1H), 7.65 (s, 1H), and 3.91 (d, J=7.2Hz, 2H), 2.24-2.19 (m, 1H), 1.32 (s, 12H), 0.90 (d, J=7.2Hz, 6H) ppm. lcms (method D, ESI): rt=1.51min, m/z=251.0[M+H]+.
