2-Furancarbonyl chloride → HCID 21081975, compound

Participants

Reaction Steps

2-Furoyl chloride (148 μL, 1.5 mmol) was added to a stirred solution of Compound 49 (380 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 ethylacetate to yield 282 mg (85%) of white solids. M.P. 248° C. 1H NMR (DMSO-d6): δ 3.68 (m, 4H), 3.96 (m, 4H), 5.47 (s, 2H), 6.66 (dd, J=1.6, 3.6 Hz, 1H), 7.08 (d, J=3.4 Hz, 1H), 7.15 (m, 2H), 7.28 (m, 2H), 7.47 (dd, J=4.7, 9.6 Hz, 1H), 7.55 (m, 1H), 7.69 (dd, J=2.8, 9.7 Hz, 1H), 7.88 (s, 1H). EIMS m/z 497 (M+23). Anal. (C26H20F2N4O3) C, H, N.
