Procedure

Thionyl chloride (1.5 mL) was added dropwise to an ice cooled methylene chloride (5 mL) solution of 3-(2-hydroxyethyl)-1,4-dimethyl-2-piperazinone (0.40 g, described in Example 1). The reaction mixture was stirred for 30 min and poured on an ice solution of 10% sodium bicarbonate. The mixture was extracted with methylene chloride, and the organic extract was dried and evaporated to give the title compound: IR (CHCl3) 1635 cm-1 ; and NMR (CDCl3) δ 2.35 (s, 3H) and 2.90 (s, 3H).
