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).
