A solution of 1.53 g (18.6 mmol) sodium acetate in water (12 mL) was added to 3.88 g (16.0 mmol) 3-chloro-N′-{[(2R)-2-hydroxypropanoyl]oxy}benzenecarboximidamide dissolved in ethanol (50 mL). The mixture was heated to 90° C. for 5.5 h and then evaporated to dryness and purified via flash chromatography (Hep/EA=9/1) to give after drying 2.3 g (65%) of the title compound. 1H NMR: 8.09 (t, 1 H), 7.97 (td, 1 H), 7.45-7.51 (m, 1 H), 7.42 (t, 1 H), 5.15 (qd, 1 H), 2.57 (d, 1 H), 1.72 (d, 3 H)
