Procedimiento

2-Furoyl chloride (118 μL, 1.2 mmol) was added to a stirred solution of Compound 27 (300 mg, 0.8 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 hexane and ether to yield 320 mg (85%) of white solids. M.P. 276° C. 1H NMR (DMSO-d6): δ 2.37 (s, 3H), 3.69 (m, 4H), 3.97 (m, 4H), 5.45 (s, 2H), 6.67 (dd, J=1.7, 3.7 Hz, 1H), 7.09 (d, J=3.4 Hz, 1H), 7.12 (m, 2H), 7.26 (m, 2H), 7.35 (d, J=8.7 Hz, 1H), 7.45 (d, J=8.8 Hz, 1H), 7.71 (s, 1H), 7.89 (s, 1H). EIMS m/z 493 (M+23). Anal. (C27H23FN4O3) C, H, N.
