Reaction Steps

A suspension of EXAMPLE 176E (35.5 mg) in tetrahydrofuran (3 mL) and HCl (1.25M in methanol, 2 mL) was stirred for 1 hour at 60° C. The product was concentrated. The crude product was purified by RP HPLC (C8, 30%-100% CH3CN/water/0.1% TFA) to yield the product. 1H NMR (300 MHz, dimethylsulfoxide-d6) δ 9.31 (s, 1H), 8.10 (s, 1H), 7.66-7.73 (m, 2H), 7.56 (d, 1H), 7.34-7.38 (m, 2H), 7.02-7.09 (m, 2H), 6.95-7.02 (m, 1H), 6.65 (dd, 1H), 6.34 (s, 1H), 6.29 (d, 1H), 6.20 (d, 1H), 6.14 (d, 1H), 4.14 (dd, 1H), 3.75 (s, 1H), 3.05 (d, 4H), 2.68-2.80 (m, 3H), 2.20 (d, 6H), 2.08 (d, 2H), 1.97 (s, 2H), 1.69-1.79 (m, 2H), 1.63 (s, 1H), 1.39 (d, 2H), 1.21-1.36 (m, 9H), 0.94 (s, 6H).
