Reaction Conditions

Reaction Steps

To N-Naphthalen-1-yl-oxalamic acid methyl ester (0.14 g, 0.61 mmol) stirring in THF (2 mL) was added 2 mL of a IN lithium hydroxide solution. The reaction was heated to 50° C. and stirred for 2 h. The resulting mixture was concentrated in vacuo to afford a yellow residue that was acidified with 1N HCL. The resulting mixture was extracted with DCM (3×50 mL), dried over MgSO4 and concentrated under vacuum to afford crude product. The crude material was purified by flash chromatography (0-20% MeOH:DCM, silica gel) to afford the desired product (0.128 g, 98%) as a thick oil. Expected mass=215. Observed mass=216.
