Versuchsvorschrift

Cyanuric chloride (200 mg, 1.1 mmol) was added to N,N-dimethylformamide (0.083 mL, 1.1 mmol) at room temperature. After the formation of a white solid (ca. 10 minutes), methylene chloride (5 mL) was added, followed by benzyl 3-[3-chloro-6-ethoxy-5-(1-hydroxyethyl)-2-methylphenyl]azetidine-1-carboxylate (310 mg, 0.77 mmol). After addition, the resultant mixture was stirred at room temperature overnight. Water was added, and then diluted with dichloromethane. The organic phases were washed with sat. NaHCO3 solution, water and brine, dried over MgSO4, concentrated and purified on silica gel (eluting with 0 to 40% EtOAc/hexanes) to give the desired product (140 mg, 43%). LCMS calculated for C22H26Cl2NO3 (M+H)+: m/z=422.1; Found: 422.0.
