Reaction Steps

Compound D (1.00 g, 2.56 mmol, 1.00 eq) was suspended in 7N ammonia in methanol (30 mL) in a microwave vial and the reaction was heated in a microwave reactor at 150° C. for 60 minutes. The reaction was concentrated to afford 881 mg (95%) of the title compound as a brown solid that was used without further purification. 1H NMR (400 MHz, DMSO-d6) δ 9.08 (d, J=4.0 Hz, 1H), 8.57 (s, 1H), 8.43 (d, J=2.4 Hz, 1H), 7.85 (dd, J=9.1, 2.4 Hz, 1H), 7.77-7.73 (m, 2H), 7.66 (d, J=4.1 Hz, 1H), 7.56-7.50 (m, 2H), 7.02 (d, J=9.1 Hz, 1H); ES-MS [M+1]+: 361.2.
