Methyl chloroformate (6.0 μL) was added to a mixture of 8-(5-amino-3-methylpyridin-2-yl)-2-(cis-4-hydroxycyclohexyl)-2,8-diazaspiro[4.5]decan-1-one (18.0 mg) and N,N-diisopropylethylamine (20.0 μL) in acetonitrile (1.0 mL). The mixture was stirred for 2 h, and was diluted with methanol. The resulting solution was purified by prep-HPLC under basic condition to afford methyl {6-[2-(cis-4-hydroxycyclohexyl)-1-oxo-2,8-diazaspiro[4.5]dec-8-yl]-5-methylpyridin-3-yl}carbamate. LCMS: (M+H)+=416.2.
