Procedimiento

In an alternative procedure, MI-773 (77 mg) was dissolved in 15 mL MeOH/H2O (v/v=1:1). After 3 days, the needle crystals that had formed were collected, washed with cold MeOH/H2O (v/v=1:1) and dried in vacuum to give MI-77301 as the free amine (20 mg; >95% purity as determined by HPLC). 1H NMR (300 MHz, MeOH-d4): 7.49-7.55 (m, 1H), 7.25-7.31 (m, 1H), 7.10-7.16 (m, 1H), 6.82 (d, J=1.8 Hz, 1H), 6.50-6.71 (m, 1H), 6.49 (d, J=8.4 Hz, 1H), 4.32 (d, J=9.0 Hz, 1H), 4.09 (d, J=8.7 Hz, 1H), 3.57-3.69 (m, 1H), 3.49 (d, J=9.2 Hz, 1H), 3.46-3.57 (m, 1H), 1.83-2.07 (m, 3H), 1.68-1.80 (m, 1H), 1.54 (dd, J=9.0, 14.3 Hz, 1H), 1.12-1.45 (m, 5H), 0.80 (s, 9H). The absolute stereochemical configuration of MI-77301 was determined by X-ray analysis.
