c. Preparation of 1,1-dioxo-1lambda6-thiomorpholine-4-carboxylic acid 3-chloropropyl ester In a 500 mL flask, thiomorpholine dioxide (13.5 g, 100 mmol) was dissolved in dichloromethane (150 mL) at room temperature and N,N-diisopropylethylamine (19.2 mL, 110 mmol) was added. After stirring at room temperature for 10 min, the reaction mixture was cooled in an ice bath to approximately 5¡ã C. To the reaction mixture, was added 1-chloro-3-chloromethoxypropane (11.8 mL, 100 mmol) via addition funnel at a rate which maintained the reaction temperature below 10¡ã C. When the addition was complete, the reaction mixture was allowed to warm to room temperature. The reaction mixture was washed with water (2*100 mL), and the organic phase dried over anhydrous sodium sulfate (25 g). After filtration, the solvent was removed by distillation to yield the title compound as an oily solid that solidified upon standing (24.0 g, 94percent yield).
