Reaction Steps

212 mg (0.48 mmol) of N-[2-(3-hydroxypropoxy)methyl-6-methylthiophenyl]-2-(9H-xanthen-9-yl)acetamide (prepared as described in Preparation 4) were suspended in 15 ml of methylene chloride. The suspension was cooled on an ice bath, and then 102 mg (0.89 mmol) of methanesulfonyl chloride were added, followed by 94 mg (0.90 mmol) of triethylamine. The temperature of the reaction mixture was allowed to rise to room temperature, after which the mixture was stirred for an additional 1 hour. At the end of this time, the reaction was stopped by the addition of water. The mixture was then diluted with methylene chloride, after which the organic layer was washed with dilute aqueous hydrochloric acid and then with water. The solvent was then removed by distillation under reduced pressure, to obtain 251 mg (a quantitative yield) of the title compound as crystals. These crystals were used for the next step without purification.
