Acetyl chloride → HCID 59598523, compound

Participants

Reaction Steps

To a solution of (3R)-tert-butyl 3-((R)-(2-aminoethoxy)(6-fluoro-3′-methylbiphenyl-2-yl)methyl)piperidine-1-carboxylate (86 mg, 0.2 mmol) in anhydrous CH2Cl2 (8 mL) was added Et3N (0.5 ml, 20 mmol). The mixture was cooled with an ice bath and acetyl chloride (15 mg, 0.2 mmol) in CH2Cl2 (4 mL) was added. The reaction mixture was stirred at rt for 0.5 h, then washed with water, dried over MgSO4, filtered and concentrated to give (3R)-tert-butyl 3-((R)-(2-acetamidoethoxy)(6-fluoro-3′-methylbiphenyl-2-yl)methyl)piperidine-1-carboxylate (80 mg, 85%), which was used in the next step without purification.
