Participants

Reaction Steps

A solution of 4-azaindole (1.0 eq.) in ether is treated with methyl magnesium iodide (1.1 eq.) at room temperature, stirred for 1 h, treated with zinc chloride (1.2 eq.), stirred for a further 1 h, treated with oxalyl chloride (10 eq.), stirred for 10 h and concentrated in vacuo to give a residue. The residue is dissolved in acetonitrile and pyridine (1.6 eq.), treated with ammonia (2 eq., solution in dioxane), stirred for 1 h and concentrated in vacuo. The concentrate is purified by chromatography [silica gel, CH2Cl2/methanol (containing 5% ammonium hydroxide) as eluent] to afford the title acetamide compound.
