Participants

Reaction Steps

To a 0° C. solution of methanol (2.22 mL, 55 mmol) was added acetyl chloride (0.868 mL, 12.21 mmol) dropwise. This methanolic HCl solution was added to a room temperature mixture of Example 62C (2.14 g, 6.11 mmol) in methyl tert-butyl ether (20 mL). After 2 hours the solid was collected by filtration (200 mL MTBE wash) and dried at 60° C. overnight in a vacuum oven to provide the title compound (2.14 g, 6.11 mmol). 1H NMR (300 MHz, DMSO-d6) δ 8.97 (bs, 2H), 8.43 (d, J=7.8 Hz, 1H), 7.62 (d, J=7.7 Hz, 1H), 4.75-4.66 (m, 1H), 2.51-2.36 (m, 2H), 1.50 (s, 3H), 1.30 (s, 3H). MS (ESI+) m/z 247 (M+H)+.
