Reaction Steps

This synthesis could be achieved beginning with a standard nitration of 2-ethylindole using sodium nitrate and sulfuric acid similar to that cited in Yokoyama; Tanaka; Yamane; Kurita; Chem. Lett.; 7; 1991; 1125-1128. The resultant 5-nitro-2-ethylindole could be reduced to the desired amino compound using catalytic hydrogenation as in 28b).
