Procedure

To a suspension of 8-(3-(aminomethyl)phenyl)-6-methyl-N-(1-(6-methylpyrimidin-4-yl)piperidin-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-2-amine dihydrochloride (37 mg, 73.8 μmol) in dichloromethane (0.75 mL) was added N,N-diisopropylethylamine (38.1 mg, 51.5 μL, 295 mmol). To the resulting yellow solution was added ethyl chloroformate (8.99 mg, 7.89 μL, 81.2 mmol) and the reaction was stirred at room temperature over night. The title compound was obtained as a light yellow solid (35 mg, 95%) after column chromatography on silica gel using a gradient from methylene chloride to a mixture of methylene chloride/methanol 19:1 (v/v) as eluent. MS ISP (m/e): 501.2 (100) [(M+H)+]. 1H NMR (CDCl3, 300 MHz): (ppm)=8.51 (s, 1H), 8.13 (s, 1H), 7.83 (br s, 2H), 7.44 (t, 1H), 7.36 (s, 1H), 7.33 (d, 1H), 6.41 (s, 1H), 5.08 (br m, 1H), 4.53 (br d, 1H), 4.44 (d, 2H), 4.32 (br d, 2H), 4.15 (q, 2H), 3.96 (m, 1H), 3.69 (m, 1H), 3.20 (t, 2H), 3.10 (m, 1H), 2.40 (s, 3H), 2.38 (s, 3H), 2.22 (br d, 2H), 1.25 (t, 3H).
