Reaction Steps

Into a 20 mL vial with a stir bar was added P-196 (132 mg, 0.37 mmol) and concentrated HCl (2 mL). The reaction was stirred at rt for 18 hours, basified with 4N aqueous NaOH, and the product was extracted with ethyl acetate (3×5 mL). The combined organics were concentrated to half their original volume and 5 mL of hexane was added. The resulting solids were filtered, washed with hexane, and triturated with ether to afford 29.8 mg (22%) of P-207 as a tan solid. 1H NMR (400 MHz, DMSO-d6) 8.28 (s, 1H), 8.20 (dd, J=1.4, 8.3 Hz, 1H), 8.05 (br. s., 1H), 7.93 (t, J=7.4 Hz, 2H), 7.72 (t, J=8.0 Hz, 1H), 7.61 (br s, 1H), 7.48 (d, J=2.0 Hz, 1H), 7.42 (dd, J=2.1, 8.5 Hz, 1H), 7.15 (d, J=8.5 Hz, 1H), 6.84 (d, J=1.5 Hz, 1H), 6.54 (dd, J=1.8, 7.0 Hz, 1H), 5.10 (s, 2H), 3.79 (s, 3H) ppm.
