HCID 593527215-(2-methoxyethoxy)-1'-[2-(2-methoxyethoxy)ethyl]spiro[1-benzofuran-3,3'-indol]-2'(1'H)-one

Procedure

Following the procedure as described in EXAMPLE 9.70 and making non-critical variations using 5-(2-methoxyethoxy)spiro[1-benzofuran-3,3′-indol]-2′(1′H)-one to replace (8S)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one, 5-(2-methoxyethoxy)-1′-[2-(2-methoxyethoxy)ethyl]spiro[1-benzofuran-3,3′-indol]-2′(1′H)-one was obtained (80%) as a colorless oil: 1H NMR (300 MHz, DMSO-d6) δ7.31-7.27 (m, 1H), 7.15-7.10 (m, 1H), 7.06-6.99 (m, 2H), 6.63-6.58 (m, 1H), 6.56-6.53 (m, 1H), 6.42-6.36 (m, 1H), 4.81 (ABq, 2H), 4.11-4.02 (m, 2H), 3.83-3.76 (m, 2H), 3.75-3.70 (m, 2H), 3.69-3.54 (m, 4H), 3.52-3.45 (m, 2H), 3.43 (s, 3H), 3.33 (s, 3H); MS (ES+) m/z 414.1 (M+1).
