    • Procedure for the Preparation of 13 To a solution of 12 (500 mg, 2.06 mmol) in DCE (10 mL) was added 4-hydroxy-7-N,N-dimethylaminocoumarin (423 mg, 2.06 mmol) and a catalytic amount of PTSA. After the mixture was stirred at 50°C for 6 h, H2O (5 mL) was added to the mixture and the product was extracted twice with CH 2Cl2. The combined organic extracts were dried over anhyd MgSO4, filtered, and concentrated. The resulting crude product was purified by column chromatography (EtOAc-hexane, 7:15) to give a blue solid with a 35% yield; mp 258-259°C. 1H NMR (300 MHz, CDCl3, δ, 9.62 (s, 1 H, 8.34 (dd, J, 8.4, 1.2 Hz, 1 H, 7.98 (d, J, 8.7 Hz, 1 H, 7.90 (dd, J, 8.1, 1.2 Hz, 1 H, 7.87-7.84 (m, 2 H, 7.74 (ddd, J, 8.1, 7.2, 1.2 Hz, 1 H, 7.63-7.52 (m, 4 H, 6.60 (dd, J, 9.0, 2.4 Hz, 1 H, 6.42 (d, J, 2.4 Hz, 1 H, 3.09 s, 6 H, 13C
