Reaction Steps

(R)-N,N-Diethyl-2-chloropropionamide (20 g) dissolved in ethanol (30 cc) is added to a suspension of the potassium salt of thiolacetic acid (16 g) in ethanol (70 cc). The reaction mixture is then heated for 2 hours at a temperature in the vicinity of 55° C. and then concentrated to dryness under reduced pressure (130 Pa) at a temperature in the vicinity of 60° C. The residue obtained is crushed in dichloromethane (300 cc) and then washed with distilled water (200 cc). The organic phase is decanted, dried over sodium sulphate, filtered and then concentrated to dryness under reduced pressure (2.7 kPa) at a temperature in the vicinity of 30° C. The residue obtained is distilled under reduced pressure (17 Pa). (S)-N,N-Diethyl-2-acetylthiopropionamide (22 g) in the form of a slightly yellow oil [b.p.17Pa =105°-107° C.; [α]D20 =-169° (c=10; CHCl3)] is thereby obtained.
