反応手順

13 g (0.2 mole) ethylmercaptan and 20 g (0.2 mole) triethylamine are added to 41 g (0.2 mole) 2-chloroethanephosphonic acid N-monoisopropylamide chloride in 100 ml benzene. Stirring was afterwards effected for 2 hours at 40° C; the salts were then filtered off with suction, the reaction solution was washed with water, and drying with sodium sulfate was carried out. After the solvent had been drawn off, there remained behind a crystalline residue, m.p. 51° C, yield: 15 g (33%) 2-chloroethanethiophosphonic acid S-ethyl ester N-monoisopropylamide.
