Reaction Steps

2-Methylthio-5-(3-pyridylmethyl)-4-pyrimidone (23.3 g) and 5-aminopentanol (24.5 g) were fused together at 170°-180° for 2 hours. Water was added to the cooled residue and the mixture was adjusted to pH7 with dilute hydrochloric acid. The solid (23.8 g) which crystallised out was recrystallised from 2-propanol containing hydrogen chloride to give 2-(5-hydroxypentylamino)-5-(3-pyridylmethyl)-4-pyrimidone dihydrochloride, m.p. 203°-205°.
