Procedure
Following the procedure as described in PREPARATION 17B, and making non-critical variations using 3-(5-bromo-2-hydroxyphenyl)-3-hydroxy-1-((5-(trifluoromethyl)furan-2-yl)methyl)indolin-2-one to replace 741-(diphenylmethyl)-3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl]-6-hydroxy-4-methyl-2H-1,4-benzoxazin-3(4H)-one, 3-(5-bromo-2-hydroxyphenyl)-1-{[5-(trifluoromethyl)furan-2-yl]methyl}-1,3-dihydro-2H-indol-2-one was obtained (89%) as a colorless solid: 1H NMR (300 MHz, CDCl3) δ8.78 (br s, 1H), 7.44-7.36 (m, 1H), 7.36-7.19 (m, 3H), 7.08 (d, J=7.9 Hz, 1H), 6.99 (d, J=2.3 Hz, 1H), 6.94 (d, J=8.5 Hz, 1H), 6.73-6.68 (m, 1H), 6.37-6.32 (m, 1H), 5.10 (s, 1H), 5.00-4.85 (m, 2H); MS (ES+) m/z 452.0 (M+1).
