실험 절차

Following the procedure as described in EXAMPLE 4 and making non-critical variations using 2-(bromomethyl)pyridine hydrobromide to replace 2-(bromomethyl)tetrahydro-2H-pyran, and 4′-bromo-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace 5,6-dihydrospiro[benzo[1,2-b:5,4-b′]difuran-3,3′-indol]-2″(1′H)-one, 4′-bromo-1′-(pyridin-2-ylmethyl)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (75%) as a colorless solid: MS (ES+) m/z 465.7 (M+1), 466.7 (M+1).
