Reaction Steps

A mixture of Example 97 (150 mg, 0.37 mmol), ethoxyethanol and liquid ammonia was heated in a sealed vessel at 80° C. at 400 psi for 16 h. The mixture was concentrated in vacuo and the solid recrystallised from MeOH to give the title compound as a yellow solid (92 mg, 66%). δH (DMSO-d6) 8.05 (1H, s), 7.68-7.59 (3H, m), 7.53-7.51 (2H, m), 7.5 (1H, br), 7.24-7.20 (2H, m), 6.80 (1H, t, J 7.3 Hz), 6.64 (2H, d, J 7.7 Hz), 6.29 (1H, s), 2.22 (3H, s). LCMS (ES+) RT 3.074 minutes, 375.9 (M+H)+
