実験手順
The m-AMSA methanesulfonate salt was prepared by slurrying 1 g of m-AMSA base in 125 ml of acetone for 20 minutes. The resulting near solution was vacuum filtered to remove undissolved solids. The solids remaining in the filter were washed with 10 ml of acetone and the wash solution was added to the original filtrate. To the above solution of m-AMSA base there was added with rapid stirring 0.24 ml of methanesulfonic acid over a three minute interval. Crystals formed and the mixture was stirred five additional minutes. The crystals were then vacuum filtered, washed with two 20 ml portions of acetone and vacuum dried at 50° C. for 24 hours to give 1.18 g of m-AMSA methanesulfonate (1:1) salt.
