Aluminium lithium hydride → HCID 11514269, compound

Participants

Reaction Steps

1.0M Lithium aluminum hydride in tetrahydrofuran (5 mL) was added to a solution of acetic acid 4-[4-(2-ethoxycarbonylamino-ethyl)-phenoxy]-phenyl ester (330 mg, 1.0 mmol) in tetrahydrofuran (25 mL). Refluxed overnight, cooled to room temperature, then quenched the reaction with saturated aqueous ammonium chloride and stirred for 3 hours. Decanted the organic layer. Washed the remaining solid with ethyl acetate (2×30 mL). Combined all the organic washes then concentrated on a rotary evaporator to yield 4-[4-(2-Methylamino-ethyl)-phenoxy]-phenol (200 mg): HPLC=98% (5/95 to 95/5 ACN/(0.1% TFA in water) over 10 minutes, Zorbax SB-Phenyl 4.6 mm×15 cm×5 micron, λ=254 nM. 1H NMR (CDCl3, 300.00 MHz): 7.42-6.77 (m, 8H), 4.32 (s, 1H), 2.95-2.79 (m, 4H), 2.52 (s, 3H).
