Reaction Steps
To 3-(5-Chloro-2-hydroxy-phenoxy)-azetidine-1-carboxylic acid tert-butyl ester (1.1 g, 3.7 mmol) in DMF (18 mL) was added Cs2CO3 (1.5 g, 4.4 mmol) and bromophenylacetic acid methyl ester (0.92 g, 0.63 mL, 4.0 mmol). After 15 h, H2O was added and the mixture extracted with EtOAc (2×). The combined organics were washed with brine and dried. Silica gel chromatography (5-25% EtOAc in hexanes) gave 1.6 g (96%) of the title compound. 1H NMR (CDCl3): 7.55-7.33 (m, 2H), 7.43-7.36 (m, 3H), 6.85 (d, J=1.2, 2H), 6.51 (t, J=1.2 Hz, 1H), 5.58 (s, 1H), 4.91-4.85 (m, 1H), 4.31-4.26 (m, 2H), 3.98-3.93 (m, 2H), 3.89-3.74 (m, 3H), 1.46 (s, 9H).
