Reaction Steps

To a solution of 2,2-dimethyl-4-oxo-4H-1,3-benzodioxine-6-carbonitrile (12 g, 0.06 mol) in methanol (500 mL) was added glacial acetic acid (3.5 g, 0.059 mol) and passed N2 for 30 min. To this was added Pd/C (2.4 g, 20%) and hydrogenated under 2 Bars of pressure for 22 h. The reaction mixture was filtered through celite and filtrate concentrated under vacuum. To the solid was added EtOAc (200 mL), stirred for 20 h and filtered. The solid was dried under vacuum to give the title compound (6 g, 38%). TLC: CHCl3/MeOH, 9:1, Rf: 0.15
