Triethylamine → HCID 73853505, compound

Participants

Reaction Steps

To a suspension of hydroxylamine hydrochloride (365 mg, 5.25 mmol) in EtOH (3 mL) was added Et3N (0.78 mL, 5.6 mmol) at room temperature under argon. A white precipitate formed. It was stirred at that temperature for 40 minutes. Then 4-[(tetrahydro-2H-pyran-2-yloxy)methyl]benzonitrile (Intermediate 26; 0.76 g, 3.5 mmol) in EtOH (2 mL) was added dropwise; the reaction mixture became clear. It was stirred at RT overnight. The crude obtained was purified by column chromatography with CH2Cl2 (A) and CH2Cl2/MeOH (95:5) (B) as eluents (0% to 80% B). The appropriate fractions were collected and the solvent removed to afford 1.25 g of sticky oil with some solids. It was dissolved in EtOAc/H2O (1:1, 150 mL). The organic layer was washed again with H2O (50 mL) and brine. It was dried over sodium sulphate, filtered and evaporated to afford the title compound (840 mg, 95%) as sticky oil.
