A mixture of 3.0 g. of 4-nitrobenzofuran, 0.5 g of 5% Rhodium on carbon and 25 ml. of ethanol is hydrogenated in a Parr apparatus at a hydrogen pressure of 50 p.s.i. and temperature of 35°C. until the uptake of hydrogen ceases. The catalyst is removed by filtration and the filtrate evaporated in vacuo to obtain an oil of 2,3-dihydro-4-benzofuranamine.
