Yield:627543-03-7 90%

Reaction Conditions:

with hydrazine hydrate in ethanol; for 2 h;Reflux;

Steps:

General procedure-5: Formation of A5 aminomethyl analogs

General procedure: (1 mmol) of compound 5 was dissolved in ethanol (5 mL), then hydrazine monohydrate (5.0 equiv) was added and the resulting reaction mixture was heated to reflux and stirred for 2 hrs. Then the reaction mixture was cooled to room temperature before DDW (10 mL) was added. The aqueous solution was then extracted with DCM (3× 10 mL), and the combined organic extracts were washed with DDW (2× 10 mL) and saturated aqueous NaCl (10 mL), dried over MgSO4, and concentrated under vacuum.
