Procedure

A mixture of the compound prepared in step c (127 mg, 0.53 mmol) and hydrazine (0.28 mL, 8.9 mmol) in dry methanol (3 mL) was stirred at reflux for 3 hr, cooled to RT and evaporated in vacuo to afford a semisolid product (0.12 g) 99%. 1H NMR (400 MHz, DMSO-d6) δ 8.12 (s, 1H), 7.90 (s, 1H), 7.76 (d, J=9.1 Hz, 1H), 7.52 (dd, J=8.5, 1.5 Hz, 1H), 7.09 (d, J=1.3 Hz, 1H)
