Reaction Steps

To a suspension of 5.5 g of Fe in 30 mL EtOH was added slowly 2 mL 12 N HCl. The mixture was stirred at 75° C. for 1 hour. After cooling at 65° C., 12 mL 25% NH4Cl solution was added. The mixture was stirred 5 min and 6a (0.02 mol, in 5 mL EtOH) was added. The mixture is heated at 75° C. for 2 hour. After cooling to rt, 5 g celite was added the mixture was filtrated on celite and the remaining solids were washed several times with ethanol. The combined filtrates were concentrated and extracted with a CH2Cl2 and 10% Na2CO3. Concentration of the organic layer led to crystallisation of the amine IIb. Yield 98%.
