Reaction Steps

A mixture of 57 mg 7-[(2,6-difluorobenzyl)oxy]-2,5-dimethylpyrazolo[1,5-a]pyridine-3-carboxylic acid (0.171 mmol) from Example 4A, 72 mg of HATU (0.188 mmol) and 0.179 ml (1.025 mmol) of N,N-diisopropylethylamine in 1.1 ml of DMF was stirred at RT for 20 min. Subsequently, 42 mg (0.205 mmol) of 2-(trifluoromethyl)piperidine-4-amine hydrochloride (Example 36A) were added and the mixture was stirred at RT overnight. The reaction mixture was admixed with water and acetonitrile and purified by means of preparative HPLC (RP18 column, eluent:acetonitrile/water gradient with addition of 0.05% formic acid). 22 mg of the target compound were obtained (27% of theory).
