Procedure

The title compound was prepared as described in Example 1 Step D using 3-(5-chloro-2-hydroxy-phenoxy)-azetidine-1-carboxylic acid tert-butyl ester (0.3 g, 1.0 mmol), the title compound of Example 75 Step A (0.75 g, 2.5 mmol), Cs2CO3 (0.80 g, 2.4 mmol) and KI (0.23 g, 1.4 mmol) in DMF (15 mL). The crude material was purified by RP HPLC to provide the title compound (0.37 g, 71%). 1H NMR (CDCl3): 7.20-6.92 (m, 1H), 6.91-6.80 (m, 2H), 6.77-6.69 (m, 1H), 6.53 (d, J=2.1 Hz, 1H), 4.87 (s, 2H), 4.79-4.69 (m, 1H), 4.27-4.12 (m, 2H), 4.00-3.88 (m, 2H), 1.38 (s, 9H).
