Procedure

Methyl 2-amino-4-chlorobenzoate (1.5 g, 8.08 mmol) in THF (15 mL) was dropwise added to the suspension of LAH (429 mg, 11.3 mmol) in THF (10 mL) under N2 at 0° C. over 10 min. The resulting mixture was stirred at room temperature for 2 hrs, then the reaction was quenched at 0° C. with saturated Na2SO4 (50 mL), extracted with Et2O (2×70 mL). The combined organic solutions were washed with brine (30 mL), dried on MgSO4, and concentrated on rotary vacuum to afford the expected product as a white solid (874 mg, 69% yield); 1H NMR (400 MHz, MeOD) δ ppm 4.50 (s, 2 H), 6.58 (dd, J=8.06, 2.01 Hz, 1 H), 6.70 (d, J=2.01 Hz, 1 H), 7.01 (d, J=8.06 Hz, 1 H); Mass spec. 157.06 (MH+), Calc. for C7H8ClNO 157.03.
