4-[(1S,2R)-2-aminocyclopropyl]phenol

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

Procedure: A solution of (trans)-2-(4-((2-methoxyethoxy)methoxy)phenyl)cyclopropanamine (Intermediate L, 62 mg, 0.26 mmol) and p-TsOH.H2O (60 mg, 0.31 mmol) in EtOH (5 mL) was heated at 75° C. for 2 h. The pH of the reaction was adjusted to 7 with NaOH (10% aqueous solution), the mixture was poured into water (10 mL) and extracted with EtOAc (4×10 mL). The organic layer was washed with brine (10 mL), dried over anhydrous Na2SO4 and filtered. After removal of the solvent a brownish residue was obtained (44 mg, 4-((trans)-2-aminocyclopropyl)phenol contaminated with p-TsOH) that was used in the next step without further purification. extracted with EtOAc (4×10 mL) The organic layer was washed with brine (10 mL) dried over anhydrous Na2SO4 filtered After removal of the solvent a brownish residue
