Hydrazine hydrate (1:1) → HCID 59320259, compound

Participants

Reaction Steps

2-Quinolin-6-yl-propionic acid (5.6 g, 26.1 mmol), hydrazine hydrate (1.6 mL) and methanol (150 mL) were combined and heated to reflux for 72 hours. After such time the mixture was concentrated in vacuo and portioned between NaHCO3 (200 mL) and dichloromethane (150 mL). The aqueous phase was extracted with dichloromethane (2×150 mL) and the combined organic extracts dried (Na2SO4) and concentrated in vacuo to return the title compound as a white solid (4.6 g, 21.4 mmol, 82%). 1H-NMR (DMSO-d6, 500 MHz): 9.30 (1H, bs), 8.85 (1H, dd), 8.33 (1H, dd), 7.95 (1H, d), 7.86 (1H, d), 7.74 (1H, dd), 7.51 (1H, dd), 4.22 (3H, s), 3.74 (1H, q), 1.44 (3H; MS: m/z 216 [M+H+]+.
