HCID 67996687HCID 67996687, compound

Procedure

A mixture of 1-(5-bromo-pyridin-2-yl)-cyclopropanecarbonitrile (0.18 g) and sulfuric acid (95%, 1.8 mL) was stirred at room temperature overnight. The solution was poured on crushed ice and the resulting solution was basified using 4 M aqueous NaOH solution. The solution was extracted with dichloromethane, the combined extracts were dried (Na2SO4), and the solvent was evaporated to give the title compound as a colorless solid. Yield: 0.20 g (quantitative); LC (method 2): tR=2.38 min; Mass spectrum (ESI+): m/z=241/243 (Br) [M+H]+.
