4-(2-aminoethyl)-2,6-difluorophenol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To lithium aluminum hydride 1.0M in ether (30 mL, 29.8 mmol) at 0° C. a solution of aluminum trichloride (4.0 g, 29.8 mmol) in THF (40 mL) is added. After 5 min a solution of compound obtained in step 1 above (2.0 g, 9.95 mmol) in THF (40 mL) is added and the reaction is allowed to stir at room temperature overnight. Add water and then 3 N HCL, the aqueous layer is extracted with 3/1 n-butanol/toluene. The combined organic layers are dried over sodium sulfate and concentrated. SCX ion-exchange chromatography afforded 1.50 g (87%) of the title compound. Electrospray MS M+1 ion=174. 1H-NMR (methanol-d4, 200 MHz): 6.95-6.78 (m, 2H), 3.14 (t, 2H, J=7.0 Hz), 2.86 (t, 2H, J=7.3 Hz). Add water and then 3 N HCL, the aqueous layer is extracted with 3/1 n-butanol/toluene The combined organic layers are dried over sodium sulfate concentrated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
