Procedure

A 10 mL reaction tube vessel was charged with compound 269 (56.0 mg, 103 μmol) and concentrated hydrochloric acid (2.00 mL, 103 μmol). The reaction was heated with microwave energy (300 W) at 120° C. for 1 hour, then an additional 30 minutes at 140° C. The resulting solution was filtered through a 0.45 μM filter and washed with water. The solvent was removed in vacuo, and the residue coevaporated with water (10 mL) and then methanol (2×, 10 mL) to give compound 270 as a yellow solid (48 mg). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.63-11.91 (m, 2 H) 9.40 (br. s., 4 H) 9.19 (s, 1 H) 8.50 (d, J=8.61 Hz, 1 H) 8.04 (d, J=2.74 Hz, 1 H) 7.99 (dd, J=9.39, 2.74 Hz, 1 H) 7.51 (d, J=9.39 Hz, 1 H) 6.69-6.78 (m, 1 H) 5.35 (quin, J=8.71 Hz, 1 H) 3.37-3.51 (m, 4 H) 3.20-3.34 (m, 4 H) 2.06-2.18 (m, 2 H) 1.93-2.06 (m, 2 H) 1.66-1.82 (m, 2 H) ppm.
