Reaktionsschritte
The procedure similar to that described in Reference Example 1 was repeated except that 1.55 g (6.57 mmol) of Compound g prepared above and 2.86 g (16.4 mmol) of sodium hydrosulfite were employed in place of 6-amino-1,3-bis(cyclopropylmethyl)uracil and sodium nitrite, respectively. As a result, 1.24 g (yield: 75%) of Compound d was obtained as white powder.
