실험 절차

3 g of 2-amino-4-chloro-5-(3,4,5-trimethoxybenzyl)-pyrimidine is added to a methanolic hydroxylamine solution prepared from 1.4 g of hydroxylamine-hydrochloride, 0.46 g of sodium and 50 ml of absolute methanol. The mixture is stirred for 48 hours at 40°; it is subsequently concentrated in vacuo and the residue is recrystallised from butanol to obtain 2-amino-4-(hydroxyamino)-5-(3,4,5-trimethoxybenzyl)-pyrimidine, M.P. 208°-210°, which is identical to the product described in Example 2.
