Procedure
Example ER-896389 was prepared in two steps from compound 3-(5-(3,4-dimethoxyphenyl)-7-(trifluoromethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-2-yl)benzoic acid (25 mg, 0.056 mmol) and commercially available tert-butyl ((3R,5S)-5-methylpiperidin-3-yl)carbamate (48 mg, 0.224 mmol) in a manner similar to that of example D-6 to afford intermediate tert-butyl ((3R,5S)-1-(3-(5-(3,4-dimethoxyphenyl)-7-(trifluoromethyl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidin-2-yl)benzoyl)-5-methylpiperidin-3-yl)carbamate (22 mg, 0.034 mmol, 61% yield). Then, this intermediate (20 mg, 0.031 mmol) was treated with HCl in a manner similar to that of example ER-897560 to afford the desired product ER-896389 (17.5 mg, 97% yield).
