Procedure

To the product of Example 205 (0.020 g, 0.047 mmol) in pyridine (0.5 mL) was added acetic anhydride (0.057 g, 0.0053 mL, 0.056 mmol). The reaction mixture was heated in a microwave reactor at 100° C. for 30 minutes. The reaction was poured into 30 mL of water. The solid was collected by filtration to give the title compound (15.8 mg, 72%). 1H NMR (300 MHz, DMSO-d6) δ 0.98 (d, J=6.62 Hz, 6 H) 1.57 (m, 2 H) 1.70 (m, 1 H) 2.10 (s, 3 H) 4.48 (m, 2 H) 7.48 (dd, J=8.09, 4.78 Hz, 1 H) 7.66 (d, J=8.82 Hz, 1 H) 7.78 (m, 1 H) 8.30 (d, J=1.84 Hz, 1 H) 8.55 (dd, J=7.72, 1.84 Hz, 1 H) 8.87 (dd, J=4.60, 1.65 Hz, 1 H) 10.39 (s, 1 H) 14.21 (br s, 1 H).
