2-Furancarbonyl chloride → HCID 21081914, compound

Participants

Reaction Steps

2-Furoyl chloride (148 μL, 1.5 mmol) was added to a stirred solution of Compound 48 (363 mg, 1 mmol) in pyridine (5 mL) under argon at 0° C. The solution was allowed to come to room temperature and further stirred overnight. The solution was poured into ice water and the solids formed were filtered. The solids were washed by excess water, dried, and recrystallized by ethyl acetate to yield 332 mg (73%) of white solids. M.P. 209° C. 1H NMR (DMSO-d6): δ 3.69 (m, 4H), 3.97 (m, 4H), 5.49 (s, 2H), 6.66 (m, 1H), 7.09 (d, J=3.3 Hz, 1H), 7.22 (m, 3H), 7.32 (m, 2H), 7.45 (dd, J=4.7, 9.5 Hz, 1H), 7.55 (m, 1H), 7.69 (dd, J=2.8, 9.7 Hz, 1H), 7.88 (s, 1H). EIMS m/z 479 (M+23). Anal. (C26H21FN4O3) C, H, N.
