Following the procedure as described in PREPARATION 9B, and making non-critical variations using 3-hydroxy-3-(7-hydroxy-4H-1,3-benzodioxin-6-yl)-1-[(2R)-tetrahydrofuran-2-ylmethyl]-1,3-dihydro-2H-indol-2-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, 3-(7-hydroxy-4H-1,3-benzodioxin-6-yl)-1-[(2R)-tetrahydrofuran-2-ylmethyl]-1,3-dihydro-2H-indol-2-one was obtained (84%) as a colorless solid: MS (ES+) m/z 368.2 (M+1).
