Versuchsvorschrift
Following the procedure as described in PREPARATION 9B, and making non-critical variations using 6-[1-(diphenylmethyl)-3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl]-5-hydroxy-3-methyl-1,3-benzoxazol-2(3H)-one to replace 3-hydroxy-3-(6-hydroxy-3-methyl-1,2-benzisoxazol-5-yl)-1-(4-methoxybenzyl)-1,3-dihydro-2H-indol-2-one, 6-[1-(diphenylmethyl)-2-oxo-2,3-dihydro-1H-indol-3-yl]-5-hydroxy-3-methyl-1,3-benzoxazol-2(3H)-one was obtained (98%) as a yellow amorphous solid: MS (ES+) m/z 463.4 (M+1).
