Procedure

To a solution of 306 (0.275 g, 0.675 mmol) in DME (5 mL) was added 10% aq HCl (5 mL). The reaction mixture was allowed to stir and heat at 80° C. for 18 hours before cooling, concentrating under reduced pressure, and diluting with EtOAc. The solution was washed sequentially with water, and brine, before drying over MgSO4 and concentrating under reduced pressure to 50 mL of EtOAc and the solids were collected by filtration to give 330 (244 mg, 89%). 1H NMR (400 MHz, DMSO) δ 11.79 (s, 1H), 9.00 (t, J=15.9, 1H), 8.10 (s, 1H), 7.67 (ddd, J=16.8, 8.8, 5.2, 2H), 7.37 (d, J=5.1, 1H), 7.08 (d, J=8.4, 1H), 6.31 (t, J=6.7, 1H), 5.88 (dt, J=13.2, 6.6, 1H), 4.58-4.20 (m, 2H), 3.46 (t, J=5.0, 2H), 1.55 (d, J=6.6, 6H). MS (ESI(+)): m/z 406.1 (M+H)
