Reaktionsschritte

A mixture of p-tolyl acetic acid (0.027 g, 0.180 mmol) and CDI (0.036 g, 0.222 mmol) in dry DMSO (2 mL) was heated to 50° C. for 2 h prior to addition of 4-[(4-aminopiperidin-1-yl)carbonyl]-N-(2-fluoro-4-iodophenyl)pyridin-3-amine hydrochloride (described above) (0.052 g, 0.109 mmol). The contents were then stirred at room temp. After 6 h, HPLC indicated near-complete reaction. The contents were poured into water (30 mL) and extracted with ethyl acetate (30 mL). The organics were washed with brine (2×30 mL), dried over sodium sulfate and concentrated to a yellow oil. The oil was further dried under high vacuum for 2 h at 40° C. to provide the desired product as a yellow semi-solid (0.068 g, 0.119 mmol, 66%). LC/MS [8.92 min; 573 (M+1)]
