실험 절차

To a solution of 8-benzyl-10-(4-chlorophenyl)-11-oxa-3,8-diazaspiro[5.5]undecane (100 mg, 0.28 mmol) and 4-isopropoxy-3-methyl-benzoic acid (54 mg, 0.28 mmol) in DMF (1 mL) was added DIEA (98 μL, 0.56 mmol) followed by the addition of HATU (128 mg, 0.34 mmol). The reaction mixture was stirred for 10 minutes, then quenched with water and the aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with water (twice). The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography using 0 to 50% EtOAc/hexanes as eluent to obtain [8-benzyl-10-(4-chlorophenyl)-11-oxa-3,8-diazaspiro[5.5]undecan-3-yl]-(4-isopropoxy-3-methyl-phenyl)methanone (44 mg, 29%). ESI-MS m/z calc. 532.2. found 533.3 (M+1)+; Retention time: 2.17 minutes (3 min run).
