Participants

Reaction Steps

To a solution of (R/S) tert-butyl methyl(2-(methyl((3-(piperidin-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-4-yl)methyl)amino)ethyl)carbamate (200 mg, 0.46 mmol, 1.00 equiv) and triethylamine (1.14 g, 11.26 mmol, 24.52 equiv) in dichloromethane (15 mL) was added 3-methylbutanoyl chloride (67 mg, 0.56 mmol, 1.21 equiv). The resulting solution was stirred at room temperature for 2 h. The reaction was then quenched by the addition of 2 mL of water. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum to give 250 mg of crude (R/S) tert-butyl methyl(2-(methyl((3-(1-(3-methylbutanoyl)piperidin-4-yl)-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-4-yl)methyl)amino)ethyl)carbamate as a yellow solid. LCMS (method D, ESI): RT=1.22 min, m/z=520.0 [M+H]+.
