실험 절차

4-methyl morpholine (1.96 mL, 17.8 mmol) was added to a mixture of 1′-(trifluoromethyl)spiro[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine] (1.45 g, 3.56 mmol), 4-tert-butylsulfinylbenzoic acid (807 mg, 3.56 mmol), EDCI (1.03 g, 5.35 mmol), 1-hydroxybenzotriazole (723 mg, 5.35 mmol) and DMF (14.5 mL) at room temperature. The mixture was heated at 50° C. overnight before it was cooled to room temperature and partitioned between ethyl acetate and 1N HCl. The layers were separated and the aqueous layer was extracted with ethyl acetate (3×). The combined organics were washed with brine, dried over sodium sulfate, filtered and concentrated. The residue was purified by column chromatography (0-30% ethyl acetate/CH2Cl2, then 0-100% ethyl acetate/hexanes) to provide (4-tert-butylsulfinylphenyl)-[1′-(trifluoromethyl)spiro-[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine]-1-yl]methanone (831 mg, 44%) as a white solid. 1H NMR (400 MHz, DMSO) δ 7.68-7.62 (m, 4H), 7.57 (d, J=8.1 Hz, 1H), 7.33-7.26 (m, 2H), 7.24-7.17 (m, 1H), 7.02 (d, J=4.0 Hz, 1H), 6.41 (d, J=4.0 Hz, 1H), 4.52-4.37 (m, 1H), 3.49 (s, 2H), 3.26-3.13 (m, 1H), 2.16-1.96 (m, 3H), 1.96-1.80 (m, 1H), 1.09 (s, 9H). ESI-MS m/z calc. 516.2, found 517.2 (M+1)+; Retention time: 1.94 minutes (3 min run).
