in ethanol; for 20 h;Reflux;
Steps:
5.E
A solution of 2-oxocyc.obexanecarbonitrile 16 (10 g, 81.2 mmol) and methyl hydrazine 15 (3 equiv, 11.2 g) in 150 mL of absolute ethanol was refluxed for 20 hrs and was concentrated on rotavapor to dryness. The crude product was recrystallized from methanol to afford the desired product 17. (Reference for the preparation of compound 17: J. Am. Chem. Soc. 1959, 81, 2448- 2452)
