実験手順
To a solution of 109 mg of 3-hydroxyazetidine.HCl [Compound (1)] in 5 ml of ethanol was added a mixture of 133 mg of 2-methylthiazoline [Compound (2)] and sodium methoxide, and the reaction mixture was refluxed for 8 hours. After removal of the solvent under reduced pressure, the resulting residue was dissolved in chloroform and washed with 50% aqueous potassium carbonate solution. The solvent was removed under reduced pressure to give 119 mg (81.5%) of 3-hydroxy-1-(thiazolin-2-yl)azetidine [Compound (3)] as a crystaline.
