Procedure
2-[1-[2-Hydroxy-2-(4-methoxyphenyl)ethyl]-1,2,5,6-tetrahydropyrid-4-y1]-4H,6H-1,3,4-thiadiazin-5-one (150 mg, 0.43 mmol) was dissolved in methanol (5 ml), added with concentrated sulfuric acid (0.8 ml, 15 mmol) and refluxed with heating for four hours. The solution was poured into ice water and neutralized with 2N aqueous sodium hydroxide.
