Procedure
Following the procedure as described in EXAMPLE 9.70 and making non-critical variations using 2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,8′-[1,3]thiazolo[5,4-e]indol]-7′(6′H)-one to replace (8S)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one, and 2-(bromomethyl)pyridine hydrobromide to replace 1-bromo-2-(2-methoxyethoxy)ethane, 6′-(pyridin-2-ylmethyl)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,8′-[1,3]thiazolo[5,4-e]indol]-7′(6′H)-one was obtained (41%) as a colorless solid: mp 156-158° C.; 1H NMR (300 MHz, CDCl3) δ8.75 (s, 1H), 8.60-8.53 (m, 1H), 7.98 (d, J=8.2 Hz, 1H), 7.69-7.61 (m, 1H), 7.32-7.26 (m, 1H), 7.23-7.17 (m, 1H), 7.13 (d, J=8.2 Hz, 1H), 6.56 (s, 1H), 6.30 (s, 1H), 5.17 (ABq, 2H), 4.87 (ABq, 2H), 4.24-4.03 (m, 4H); MS (ES+) m/z 444.1 (M+1).
