YieldReaction ConditionsOperation in experiment
82.8% With thionyl chloride; acetic acid In tetrahydrofuran; chloroform; ethyl acetate 6.1 EXAMPLE 6 (1) To a solution of D-lactic acid O-tosylate (2g) in chloroform (20 ml) was added thionyl chloride (2.39 ml), and the mixture was heated under reflux for 3 hours. The reaction mixture was concentrated under reduced pressure, then reconcentrated with addition of chloroform to obtain an acid chloride (residue C). On the other hand, benzyl (4S)-1-methyl-2-oxoimidazolidine-4-carboxylate (2.21 g) was dissolved in tetrahydrofuran (25 ml), and under cooling at -50° C., potassium t-butoxide (1.06 g) was added under nitrogen gas stream, followed by stirring for 20 minutes. To this solution was added at the same temperature a solution of the above acid chloride (residue C) in tetrahydrofuran (4 ml), followed by stirring for 20 minutes. To the reaction mixture were added a mixed solution of ethyl acetate (15 ml), acetic acid (0.57 g) and saturated aqueous sodium chloride (15 ml). The organic layer was taken by separation, successively washed with saturated aqueous sodium chloride, aqueous 5 % potassium carbonate, saturated aqueous sodium chloride, and then dried. Evaporation of the solvent and recrystallization of the residue from ethyl acetate gave benzyl (4S)-1-methyl-3-[(2R)-2-(p-toluenesulfonyloxy)-propionyl] -2-oxoimidazolidine-4-carboxylate (3.1 g).

YieldReaction ConditionsOperation in experiment
85% With sodium tetrahydridoborate; ethanol; calcium(II) chloride at 0 - 20℃; for 12h; 365.A Example 365: (4S)-4-[[4-[2-[(2,6-dimethylpyrimidin-4-yl)amino]pyrazolo[1,5-a]pyridin-5-yl]- 6-methyl-3-pyridyl]oxymethyl]-1-methyl-imidazolidin-2-one. Step A. (S)-4-(hydroxymethyl)-1-methylimidazolidin-2-one. To a mixture of (S)-benzyl 1-methyl-2-oxoimidazolidine-4-carboxylate (340 mg, 1.45 mmol, 1 equiv.), CaCl2 (96.7 mg, 0.871 mmol, 0.6 equiv.) and EtOH (10 mL) at 0°C was added NaBH4 (66 mg, 1.7 mmol, 1.2 equiv.).The mixture was stirred at room temperature for 12 hr. The ethanol was removed under vacuum and the residue was dissolved in sat. aq. NH4Cl (5 mL). The mixture was extracted with EtOAc (20 mL x 3) and the product was detected in the aqueous phase. The aqueous phase was frozen using dry ice/ethanol, and then lyophilized to dryness to get the crude product. To the crude product was added MeOH (5 mL) and MeCN (100 mL) to remove salt. The mixture was filtered then concentrated to give the compound (S)-4-(hydroxymethyl)-1-methylimidazolidin-2- one as a colorless oil (160 mg, 85%)
