Reaction Steps
To a solution of acetic acid (20 mL) in H2O (100 mL), 7-nitro-6-methoxy-1-tetralone (2.21 g, 10.0 mmol) was added. The solution was heated to reflux for 1 hour, and then cooled down to rt. NaHCO3 (60 mL, saturated solution) was added, and the mixture was partitioned between CH2Cl2 and water. The organic layer was dried over anhydrous sodium sulfate. After filtration, the organic layer was concentrated in vacuo to provide a red oil. 7-Amino-6-methoxy-1-tetralone (1.74 g, 9.1 mmol, 91%) was obtained following purification by column chromatography. 1H-NMR (CDCl3, 300 MHz) 2.07 (m, 2H), 2.57 (t, J=6.5 Hz, 2H), 2.86 (t, J=6.0 Hz, 2H), 3.73 (b, 2H), 3.91 (s, 3H), 6.59 (s, 1H), 7.36 (s, 1H).
