実験手順

2-Aminopyrrolo[2,3-d]pyrimidin-4-one (45 g) was suspended in phosphorus oxychloride (150 ml) and the suspension was stirred at 110° C. for 3 hours. The excess amount of phosphorus oxychloride was distilled off under reduced pressure and ice water (600 ml) was added to the residue, whereby the residue was thoroughly dissolved. The solution was cooled with stirring and adjusted to pH 9 with concentrated aqueous ammonia. The resulting precipitate was collected by filtration, washed with water and recrystallized from hot methanol (4 l) to give the above-identified compound (34.6 g).
