Reaction Steps

Diethyl azodicarboxylate (0.71 ml, 4.47 mmol) was added to a solution of [3-hydroxy-3-(3-pyridinyl)propyl]carbamic acid 1,1-dimethylethyl ester (Example 58(b)) (291 mg, 1.15 mmol), 2-chloro-5-trifluoromethylphenol (232 mg, 1.18 mmol) and triphenylphosphine (455 mg, 1.73 mmol) in tetrahydrofuran (6 ml) at 0° C. and stirred at 20° C. for 18 h. The reaction was concentrated in vacuo and the residue purified by chromatography on silica, eluting with petrol—diethyl ether to afford the sub-title compound (394 mg, 79%).
