Reaction Steps

2-Methylbenzothiazole-5-ylamine (1.0 g, 4.2 mm) was suspended in a mixture of 1:1 ethyl ether: saturated aqueous sodium bicarbonate. To the suspension was added chloracetyl chloride (0.7 g, 6.5 mm) over a period of 10 minutes. The mixture was allowed to stir at room temperature for 24 hours, and then diluted with 50 ml of ethyl acetate. The organic layer was separated, dried over magnesium sulgate, and filtered. The solvent was evaporated from the filtrate, and the white solid residue obtained was triturated in ether and filtered, to afford 2-chloro-N-(2-methylbenzothiazol-5-yl)acetamide, a compound of formula (1).
