Reaction Steps

To a solution of 3-ethyl-7-nitro-3,4-dihydroisoquinoline (15.8 g, Example 2 (d)) in methanol (100 ml) at 0° C. was added sodium borohydride (4g). After foaming had stopped, the reaction was poured into water (750 ml) and then the aqueous phase was extracted with ethyl acetate (3×300 ml). Evaporation gave 3-ethyl-7-nitro-1,2,3,4-tetrahydroisoquinoline as a tan oil (15.8 g).
