Reaktionsschritte
A mixture of Example 1 and 2-amino-2-methyl-1-propanol (1.22 mL, 13 mmol) was heated at 150° C. for 16 h. The mixture was partitioned between DCM (60 mL) and 10% citric acid (75 mL). The aqueous phase was extracted with DCM (20 mL). The combined organics were dried (Na2SO4) and concentrated in vacuo. Purification by column chromatography (silica, 40% EtOAc in DCM) gave the title compound as a pale brown solid (45 mg, 16%). δH (CDCl3) 8.44 (1H, br s), 7.56-7.46 (3H, m), 7.34-7.31 (2H, m), 7.26-7.20 (3H, m), 7.03-6.96 (3H, m), 6.33 (1H, d, J 9.7 Hz), 5.65 (1H, br s), 4.21-4.18 (1H, br m), 3.49 (2H, d, J 5.5 Hz), 1.18 (6H, s). LCMS (ES+) 434 (M+H)+.
