실험 절차

1-(Benzo[b]thiophen-4-yl)propan-1-one (32.3 g; prepared in a manner similar to that described above) was reacted with phenyltrimethylammonium tribromide (63.9 g) followed by 2-imidazolidinethione (17.4 g) using methodology similar to that described in Example 9 Method A to give 3-(benzo[b]thiophen-4-yl)-2-methyl-5,6-dihydroimidazo[2,1-b]thiazole hydrobromide (46.8 g) as a colourless solid, m.p. 262-264° C. This was combined with a sample of 3-(benzo[b]thiophen-4-yl)-2-methyl-5,6-dihydroimidazo[2,1-b]thiazole hydrobromide (25.4 g) prepared according to the methodology described in Example 9 Method A. The combined sample was then basified and converted into the hydrochloride salt in a manner similar to that described in Example 9 Method A to give 3-(benzo[b]thiophen-4-yl)-2-methyl-5,6-dihydroimidazo[2,1-b]thiazole hydrochloride (46.8 g) as a colourless solid, m.p. 242-245° C.
