Reaction Steps

To a solution of 4-{5-[2-amino-5-(1-methyl-1H-indol-5-yl)-pyridin-3-yl]-[1,3,4]oxadiazol-2-yl}-piperidine-1-carboxylic acid tert-butyl ester (300 mg, 0.63 mmol) in TFA (2.0 mL) at 0° C. was added triethylsilane (146 mg, 1.26 mmol) drop-wise over a period of 5 min, and stirred for 2 h at 0° C. The reaction was diluted with water (20 mL), neutralized with saturated aqueous NaHCO3 solution and extracted with ethyl acetate (3×20 mL). The organic layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure to obtain crude product. Crude product was purified by washing with diethyl ether and hexane to afford the title compound as a yellow solid:
