Procedure

To a solution of 30 mg (0.13 mmol) of 3-(1-ethoxyethoxy)-4-phenyl-2-azetidinone 6 in 2 mL of CH2Cl2, 2 mg of DMAP and 0.05 mL of triethylamine was added at room temperature. After 5 min. 22.9 mg (0.15 mmol) of morpholinecarbonyl chloride was added. The reaction mixture was stirred for 2 h at room temperature. The reaction mixture was diluted with 20 mL of CH2Cl2 and the organic layer was washed two times with brine, dried over Na2CO3 and concentrated. The crude solid product was purified by chromatography on silica gel to yield pure 7f: 87%; pale yellow oil; 1H NMR (250 MHz, CDCl3) δ [0.90 (d, J=5.3 Hz), 1.01 (d, J=5.3 Hz) (3H)], [1.04 (t, J=7.1 Hz), 1.18 (t, J=7.1 Hz)] (3H), 3.20 (m, 4H), [3.28 (m), 3.53 (m), 3.67 (m) (2H)], 3.60 (m, 4H), [4.41 (g, J=5.3 Hz), 4.63 (q, J=5.3 Hz) (1H)], [5.07 (d, J=5.8 Hz), 5.08 (d, J=5.8 Hz) (1H], [5.29 (d, J=5.8 Hz), 5.32 (d, J=5.8 hz) (1H], 7.23-7.27 (m, 5H).
