5-(3,3-Dimethyl-but-1-ynyl)-3-[(4-hydroxy-trans-cyclohexyl)-(4-methyl-cyclohex-3-enecarbonyl)-amino]-thiophene-2-carboxylic acid methyl ester (40 mg, 0.088 mmol) and (N,N-dimethyl)-(2-fluoro-pyridin-4-ylmethyl)amine (84 mg, 0.55 mmol) in DMF (1 mL) were treated with sodium hydride (22 mg, 60% oil dispersion, 0.55 mmol). After the bubbling slowed, the reaction mixture was sealed and heated by microwave (90° C.) for 70 min. The reaction mixture was treated with 10% citric acid (2-3 mL) followed by water (2-3 mL). The organics were extracted twice with ethyl acetate, dried over sodium sulfate, filtered and concentrated. The residue was purified by reverse phase HPLC to give the Compound 337, 18 mg (35% yield): MS (m/z): 578.0 [M+H]+; HPLC retention time 3.53 min (2-98% acetonitrile:water with 0.05% trifluoroacetic acid).
