Participants

Reaction Steps

A solution of diazomethane in ether is added dropwise to a solution of 2-(3-carboxy-propylamino)-4H-3,1-benzoxazin-4-one in ether. The reaction is monitored by thin layer chromatography (silica gel, 10% ethylacetate in petroleum ether) until completion. A small amount of silica gel is added to the solution. The solution is allowed to stand for 3 hours, then filtered. The filtrate is evaporated to give 2-(3-carbomethoxypropylamino)-4H-3,1-benzoxazin-4-one.
