WebJan 31, 2006 · To a solution of compound 3 (1.0 g, 1 mmol) in ether (10 mL) cooled with ice-salt bath, was added diazomethane (~10 mmol), freshly prepared by reacting CH 3 N(NO)CONH 2 (3.0 g, 20 mmol) with KOH (2.0 g, 36 mmol) in H 2 O (3 mL) and ether (20 mL) solution and silica gel (100 mg). The mixture was stirred at r.t. for 44 hr. WebAdd solution of Diazald in ether to the reaction flask in one portion, replacing the distillation arm quickly. Note that the end of the distillation arm should be below the level of the solvent in the receiver flask.
