Example 142: 1,1,1,3,3,3-Hexafluoropropan-2-yl 1-((1-acetyl-1,2,3,4-tetrahydroquinolin-8- yl)methyl)-1,8-diazaspiro[4.5]decane-8-carboxylate Step 1: Preparation of 1-tert-butyl 8-(1,1,1,3,3,3-hexafluoropropan-2-yl) 1,8- diazaspiro[4.5]decane-1,8-dicarboxylat A flask was charged with triphosgene (2.46 g, 8.29 mmol, 0.50 equiv), DCM (100 mL) and HFIP (4.21 g, 24.9 mmol, 1.50 equiv). DIEA (6.45 g, 49.7 mmol, 3.00 equiv) was added dropwise at 0 ^C. The reaction mixture was stirred for 2 h at 0 ^C. tert-Butyl 1,8- diazaspiro[4.5]decane-1-carboxylate (4.01 g, 16.6 mmol, 1.00 equiv) was added, and the reaction was stirred for 3 h at 0 ^C before quenching with H2O (50 mL). The mixture was extracted with DCM (3 x 50 mL) and the organic layers were combined, washed with H2O (3 x 100 mL), dried over anhydrous Na2SO4, filtered, and concentrated. The residue was purified on a silica gel column (1:2 EtOAc/petroleum ether) to provide 4.34 g (60% yield) of 1-tert-butyl 8-(1,1,1,3,3,3- hexafluoropropan-2-yl) 1,8-diazaspiro[4.5]decane-1,8-dicarboxylate as a white solid. LCMS (ESI, m/z): 435 [M+H]+.
