Participants

Reaction Steps

The mixture of 5-[3-Amino-2-(tert-butyl-dimethyl-silanyloxymethyl)-phenyl]-1-methyl-3-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-1H-pyridin-2-one (0.2 g, 0.36 mmol), 4-bromo-2-(2-bromo-ethyl)-benzenesulfonyl chloride (0.4 g, 1.08 mmol) and DIPEA (1 mL) in dichloroethane (10 mL) was microwaved at 120° C. for 30 min, then added 4-bromo-2-(2-bromo-ethyl)-benzenesulfonyl chloride (0.4 g, 1.08 mmol) and DIPEA (1 mL) and microwaved at 120° C. for 30 min. After repeating this process three times, the mixture was concentrated to afford a dark residue. Purification by silica gel chromatography (methylene chloride/acetone) afforded 0.15 g of 5-[3-(6-Bromo-1,1-dioxo-3,4-dihydro-1H-1lambda*6*-benzo[e][1,2]thiazin-2-yl)-2-(tert-butyl-dimethyl-silanyloxymethyl)-phenyl]-3-[5-(morpholine-4-carbonyl)-pyridin-2-ylamino]-1H-pyridin-2-one as a pale solid MS (ESI) 796.2 (M+H)+.
