Procedure

2-(2-chlorophenylcarbamoyl)-3-methyl-5,6-dihydro-imidazo [2,1-b] thiazole hydrochloride (compound 4) (8.2 g, 0.025M) was dissolved in water (250 ml) and the insolubes were removed by filtration. To the solution was added 5% sodium hydroxide solution with stirring until an alkaline pH (pH 9-11) was reached. The precipitated crystals were filtered, washed and dried to obtain compound 3 as white powdery crystals. (7.2 g, yield: 98.2%).
