Procedure

To a solution of Example 75 (50 mg, 0.13 mmol) in NMP (2 mL) was added methylamine hydrochloride (18 mg, 0.26 mmol) and DIPEA (0.5 mL). The mixture was heated in a microwave at 220° C. for 2 h. Purification by preparative HPLC (Method 1) gave the title compound as an off-white solid (23 mg, 44%). δH (CDCl3) 8.17 (s, 1H), 7.63-7.70 (m, 3H), 7.38-7.57 (m, 5H), 5.47 (s, 1H), 4.80-4.95 (m, 2H), 4.69 (d, J 5.8 Hz, 2H), 2.91 (d, J 5.1 Hz, 3H), 2.81 (s, 3H), 2.14 (s, 3H). LCMS (ES+) 370.2 (M+H)+, RT 2.34 minutes (Method 3).
