A solution of tert-butyl N-[2-[([3-(3,5-diisopropylphenyl)-1-(oxan-2-yl)-1H-pyrazol-4-yl]methyl)(methyl)amino]ethyl]-N-methylcarbamate (180 mg, 0.35 mmol, 1.00 equiv) in a saturated hydrogen chloride solution in 1,4-dioxane (5 mL) was stirred at room temperature overnight. The resulting mixture was concentrated under vacuum and the residue was triturated with 1×50 mL of ether to give 130 mg (92%) of ([3-[3,5-bis(propan-2-yl)phenyl]-1H-pyrazol-4-yl]methyl)(methyl)[2-(methylamino)ethyl]amine as a light yellow solid. 1H NMR (300 MHz, CD3OD): δ 8.25-8.22 (m, 1H), 7.31 (s, 1H), 7.27 (s, 2H), 4.70-4.37 (m, 2H), 3.60-3.35 (m, 4H), 3.04-2.94 (m, 2H), 2.72 (s, 3H), 2.71 (s, 3H), 1.31 (d, J=7.2 Hz, 12H) ppm. LCMS (method H, ESI): RT=1.34 min, m/z=329.1 [M+H]+.
