The mixture was stirred for 30 minutes, [1,3]dioxolan-2-one was added, the mixture was stirred and slowly warmed to room temperature. The reaction was monitored by TLC. After the reaction was done, EtOAc was added, washed with saturated NaHCO3, water and brine, dried with Na2SO4, filtered and concentrated. The residue was purified by silica gel, eluants EtOAc and DCM 10%, to give 2-(4-Bromo-pyrazol-1-yl)-ethanol 0.22 g, yield 34%. 1H NMR (400 MHz, chloroform-D) 6 ppm 7.49 (s, 1 H) 7.46 (s, 1 H) 4.18 &#8211; 4.23 (m, 2 H) 3.93 &#8211; 3.98 (m, 2 H) 3.09 (s, 1 H).<\/p>\n<p>If you are interested in these compounds, you can also browse my other articles.Thank you for taking the time to read this article.
