Reaction Steps

To the suspension of 2-(7-methoxy-1-benzofuran-3-yl)ethanamine hydrochloride (from step 2) (0.432 g, 1.9 mmol) in dry THF, triethylamine (0.769 g, 7.6 mmol) was added followed by ethyl chloroformate (0.265 g, 2.4 mmol) and stirred for 18 hrs. Water was added to it and extracted with ethyl acetate. Organic layer was concentrated and purified on Silica gel column to yield Ethyl 2-(7-methoxy-1-benzofuran-3-yl)ethylcarbamate (82%).
