Procedure

Sodium hydride (60% in mineral oil; 0.042 g, 1.04 mmol) was suspended in DMF (5 mL). After stirring for 10 minutes, 2-methyl-2-propanethiol (0.13 mL, 1.15 mmol) was added, and the mixture was stirred for 30 minutes. (5-{2-[(N-Cyclopropanecarbonyl-N-ethyl-amino)-methyl]-4-fluoro-phenyl}-pyridin-3-yl)-acetic acid ethyl ester (0.20 g, 0.52 mmol) was added, and the reaction was stirred at 90° C. overnight. The mixture was diluted with H2O, and N2 was bubbled through the solution into a bleach trap until all odor was removed. The aqueous layer was washed with EtOAc, and then acidified to pH 4 and extracted with EtOAc. The combined organic layers were concentrated, and the residue was purified by preparative HPLC to give Compound 22.
