Reaction Conditions:
with hydrazine hydrate monohydrate in ethanol at 90;
Steps:
1.19
To a solution of Intermediate-14 (11 g, 26.3 mmol) in EtOH (150 mL) was added NH2NH2-H2O (85%, 7.7 g, 131 mmol). The mixture was stirred at 90° C. overnight. The mixture was filtered and rinsed with EtOH (2×50 mL). The filtrate was concentrated to give Intermediate-15 (7.6 g, yield 100%). MS (ESI+) m/z 289 ([M+1]+).
