Reaction Steps

Ethyl 4-(isopropylamino)-7-[(RS)-3-{S-methyl -N-[(4-nitrophenyl)sulphonyl]-sulphonimidoyl}propoxy]quinazoline-6-carboxylate (270 mg, 0.47 mmol) is dissolved in acetonitrile (7 ml), treated with caesium carbonate (276 mg, 0.85 mmol) and thiophenol (90 mg, 0.82 mmol) and stirred at room temperature for 20 hours. The reaction batch is diluted with water and methylene chloride. The organic phase is separated off and dried over sodium sulphate. The desired product is obtained after removal of the solvent, preparative HPLC and subsequent repeated trituration of the residue in 45% yield (83 mg).
