Benzyl Bromide → HCID 67236182, compound

Participants

Reaction Steps

A mixture of the product of Example 22B (0.72 g, 1.5 mmol), benzyl bromide (0.26 g, 1.5 mmol) and potassium carbonate (3.0 g in 3 mL of H2O) in tetrahydrofuran (6 mL) was stirred at room temperature for 72 hrs, diluted with ethyl acetate, washed with water and partitioned. The isolated organic layer was concentrated and the residue was chromatographed on silica gel, eluting with 60%-100% ethyl acetate/hexanes to afford the title compound (0.58 g, 72%) as an amorphous solid. 1H NMR (300 MHz, d6-DMSO) 9.00 (s, 1H), 8.42 (s, 1H), 7.80 (d, J=7.5 Hz, 1H), 7.68 (d, J=7.5 Hz, 1H), 7.48 (m, 1H), 7.28 (m, 5H), 6.95 (d, J=7.5 Hz, 1H), 6.83 (m, 1H), 6.58 (m, J=6.0 Hz, 1H), 6.50 (m, 1H), 6.36 (d, J=7.5 Hz, 1H), 4.64 (m, 2H), 4.01 (s, 3H), 3.57 (m, 1H), 3.41-3.20 (m, 2H), 2.90 (m, 1H), 2.67 (m, 1H), 2.03 (m, 1H), 1.82 (m, 1H); MS (DCI/NH3) m/e 470 (M+H)+.
