The titled reaction was effected with iso-amyl nitrite or sodium nitrite, both in cone. H2SO4 at 0-25 degrees C in excellent yields (55-98%). Apart from the mild temperatures employed, organic solvents and reagents can be avoided, and the by-products are CO2 and N-2, so the conditions are environment-friendly.
