Participants

Reaction Steps

A mixture of EXAMPLE 1E (0.55 g) and a 1M solution of boron tribromide in dichloromethane (25.1 mL) were stirred at ambient temperature for 3 hours. The mixture was poured into 1N hydrochloric acid and extracted with ethyl acetate. The precipitate that formed in the aqueous phase was filtered to afford the title compound. 1H NMR (DMSO-d6) δ 10.35 (s, 1H), 9.27 (s, 1H), 8.30 (d, J=6.7 Hz, 1H), 8.17 (d, J=6.7 Hz, 1H), 8.00-8.03 (m, 2H), 8.92 (s, 1H), 7.53 (t, J=7.9 Hz, 1H), 6.95-6.99 (m, 2H).
