Allyl Alcohol → HCID 58431049, compound

Participants

Reaction Steps

To a solution of 1-Pyrazin-2-yl-cyclopropanecarboxylic acid (111 mg, 0.676 mmol) in dry toluene (1.5 mL) was added TEA (0.11 mL, 0.81 mmol) followed by diphenylphosphoryl azide (DPPA, 0.16 mL, 0.74 mmol). The reaction was stirred for 1 h at rt. Allyl alcohol (0.2 mL) was added via syringe and the reaction was heated to 90° C. for 3 h. After cooling to room temperature, the reaction was diluted with water (6 mL) and EtOAc (4 mL). The layers were separated and the water layer was extracted with EtOAc (3×4 mL). The combined organic layers were dried over Na2SO4 and concentrated to give a black residue that was purified by flash chromatography (silica, 40→50% EtOAc/hexanes) to give 67 mg of the title compound as a light orange oil, m/z 220.52 [M+1]+.
