Participants

Reaction Steps

Under a nitrogen atmosphere, MTBE (3 ml) was added to 60% 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 43%) was contained.
