3-(chloromethyl)-N,N-dimethylbenzenesulfonamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following the procedure as described in EXAMPLE 7.3 and making non-critical variations using 2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace (S)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one, and 3-(chloromethyl)-N,N-dimethylbenzenesulfonamide to replace 1-bromopentane, N,N-dimethyl-3-[(2′-oxo-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-1′-(2′H)-yl)methyl]benzenesulfonamide was obtained (40%) as a colorless solid: 1H NMR (300 MHz, DMSO-d6) δ 7.72-7.62 (m, 4H), 7.29-6.99 (m, 4H), 6.50 (s, 1H), 6.07 (s, 1H), 5.06 (ABq, 2H), 4.71 (ABq, 2H), 4.19-4.05 (m, 4H), 2.50 (s, 6H); 13C NMR (75 MHz, DMSO-d6) δ 176.9, 154.7, 144.2, 141.9, 137.8, 134.9, 131.8, 131.5, 129.9, 128.8, 126.6, 125.9, 123.8, 123.2, 120.9, 110.9, 109.3, 98.8, 79.4, 64.2, 63.5, 57.2, 42.5, 37.4; MS (ES+) m/z 492.7 (M+1).
