69% | With hydrazine hydrate; In ethanol; for 3h;Reflux; | General procedure: The ester (10.0 mmol) was added in small portions to a solution of hydrazinehydrate (40.0 mmol) in 3.0 mL of ethanol. After refluxing for 3?6.5 h, the residuewas concentrated in vacuum and purified by column chromatography. |

99% | With thionyl chloride; at 0℃; for 2h;Inert atmosphere; | A 300-mL three-necked round-bottomed flask equipped with a magnetic stirring bar and fitted with a dropping funnel was charged with N-Cbz-glycine (2.50g, 12.0mmol) and methanol (60mL). The flask was cooled to 0°C, and thionyl chloride (1.20mL, 16.5mmol, 1.4equiv) was added to the vigorously stirred solution over a period of 10min. The mixture was stirred for additional 2h, after which time TLC (ethyl acetate) indicated complete consumption of the starting N-Cbz-glycine. The reaction mixture was concentrated under reduced pressure to give a crude material, which was purified by silica gel column chromatography (ethyl acetate) to afford N-Cbz-glycine methyl ester (2.66g, 11.9mmol, 99percent) as a colorless oil. Rf=0.55 (ethyl acetate). 1H NMR (400MHz, CDCl3): delta 7.32?7.18 (m, 5H), 5.58 (br s, 1H), 5.02 (s, 2H), 3.84 (d, 2H, J=5.6Hz), 3.62 (s, 3H). 13C NMR (100MHz, CDCl3): delta 170.4, 156.2, 136.1, 128.2, 127.9, 127.8, 66.7, 51.9, 42.3.

43% | Under a nitrogen atmosphere, MTBE (3 ml) was added to 60percent sodium hydride (0.10 g). Methyl-N-tert-butoxycarbonyl-glycinate (0.39 g, 2.05 mmol) and methyl formate (0.31 g, 5.13 mmol) were dissolved in MTBE (2 ml) in an ice bath and the solution was added dropwise over 1 hr. After overnight stirring at normal temperature, the precipitate was collected by filtration and the crystal and O-methylisourea hydrochloride (0.22 g, 2.05 mmol) were stirred overnight at 40 C in methanol. The reaction mixture was analyzed by HPLC. As a result, 2-methoxy-6-oxo-5-tert-butoxycarbonylamino-1,6-dihydropyrimidine (0.21 g, 0.88 mmol, yield 43percent) was contained. |

In toluene; at 70℃; | Toluene (15 ml) was added to methyl-N-benzyloxycarbonyl-glycinate (1.50 g, 6.7 mmol) and tert-butoxybisdimethylaminomethane (1.84 ml, 8.8 mmol) and the mixture was stirred overnight at 70°C. The mixture was washed with water and saturated brine at room temperature. The resultant organic layer was concentrated under reduced pressure to produce methyl-2-benzyloxycarbonylamino-3-dimethylaminoglycinate (1.83 g, 6.6 mmol). 1H-NMR (CDCl3) delta ppm: 3.01 (6H,s), 3.66 (3H,s), 5.15 (2H,s), 5.57 (1H,s), 7.26 - 7.37 (6H,m) MS (ESI) m/z [MH]+ 279.2 |
