5-Nitro-2,3-dihydro-1,4-benzodioxin (5.4 g; 29.83 mmol) was dissolved in ethanol (130 ml) and conc.HCl added (1.13 ml; 29.83 mmol) this was then stirred with 10% Pd/C under hydrogen at rt and atmospheric pressure overnight. The catalyst was then filtered off and washed with MeOH. The solvents were removed and the crude purified by SCX. Fractions containing product were concentrated to give the desired product (4.6 g).
