701-16-6, [0436] Compound 50: To a solution of Comp-50c (3.95 g, 26.15 mmol) in THF:iBuOH (50 mL 4: 1 ) was added t-BuOK (8.78 g, 78.47 mmol) and the reaction mixture was stirred for 10 min. Comp-3b (5.18 g, 23.54 mmol) was added portion wise and the reaction mixture was stirred at room temperature for 16h. Progress of the reaction was monitored by TLC and LCMS. After completion, the reaction mixture was quenched with H20 and extracted with EtOAc. The organic layer was washed with brine, separated, dried over anhydrous Na2SO4 and concentrated in vacuo. The crude obtained was purified by column chromatography (silica, 100-200 mesh, 2-3% MeOH in ethyl acetate) to afford (E)-2-(2-(2,5-dimethyl-l-(l- me1hylpiperidin-4-yl)-lH-pyrrol-3-y])viny])-5-fluorobenzo[d]oxazole (50; 1.8 g, 20%) as yellow solid.
