Sodium hydride → 2-(Azetidin-3-ylthio)-1,3-thiazolidine

To a 5 ml solution of dried tetrahydrofuran containing 550 mg (4.61 mmol) of 1,3-thiazoline-2-thione which was being cooled with ice, on the other hand, there was added 181 mg (55%) of sodium hydride, and the resulting mixture was stirred for one hour. To the obtained solution, there was added dropwise the above solution of 1-azabicyclo[1.1.0]butane dissolved in tetrahydrofuran at -78° C., and the resulting solution was stirred at a room temperature for 20 hours, and, then, the reaction liquid was subjected to high performance liquid chromatography, and, thus, there was obtained 2-(azetidin-3-ylthio)-1,3-thiazolidine (9).
