Participants

Reaction Steps

To 3-[{4-[(4-acetyl-3-hydroxy-2-methyl-phenylamino)-methyl]-phenyl}-(tetrahydro-pyran-2-yloxy)-methyl]-benzonitrile (538 mg, 1.1 mmol) in MeOH (5 mL) is added conc. HCl (0.33 mL). The reaction mixture is stirred at RT for 6 h. The reaction mixture is concentrated and the residue partitioned between saturated aqueous NaHCO3 and EtOAc. The organic layer is separated and the aqueous extracted with EtOAc (2×). The organic layers are combined, washed with brine, dried over Na2SO4, and concentrated. The residue is purified by flash column chromatography using 40% EtOAc/hexane as eluent. Obtained is the title compound as yellow foam (305 mg, 72%). LC-MS (m/e): 385 (M−1).
