1-methylpiperidine-2-carboxylic acid;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1-methyl-6-(4-(3-(methylamino)propoxy)-3-(trifluoromethyl)phenyl)-1H-imidazo[4,5-c]pyridine-4-carbonitrile (50 mg), triethylamine (71 μL), 1-methylpiperidine-2-carboxylic acid hydrochloride (17 mg), and O-benzotriazol-1-yl-N,N,N′,N′-tetramethyluronium hexafluorophosphate (58 mg) in DCM (1.5 ml) was stirred overnight at room temperature. The mixture was washed with sodium bicarbonate and then purified by prep HPLC (acidic) to give the expected product (11 mg). NMR (CD3OD) δ: 8.29-8.52 (m, 4H), 7.27-7.40 (m, 1H), 4.16-4.36 (m, 2H), 4.06 (s, 3H), 3.58-3.92 (m, 2H), 2.86-3.27 (m, 5H), 2.14-2.37 (m, 6H), 1.26-1.90 (m, 6H). MS m/z 515 (M+H). The mixture was washed with sodium bicarbonate purified by prep HPLC (acidic)
