The compounds of the formulas (VI) and (VII) are useful intermediates in producing pyridyloxy derivatives of the formula (I), such as, for instance, N-4-[4-(piperidinomethyl)pyridyl-2-oxy]-2-butenyl}-2-(furfurylt hio)acetamide, which are useful as anti-peptic ulcer agents. The compounds of formula (VI) have the formula ##STR1## wherein A represents a formyl group, a protected formyl group, a hydroxymethyl group or a protected hydroxymethyl group. The compounds of formula (VIII) have the formula ##STR2## wherein G represents a formyl group, a protected formyl group, a hydroxymethyl group, a hydroxymethyl group in which the hydroxyl group is protected, or a halogenomethyl group, Y represents --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--, and n is 0, 1 or 2.
公式(VI)和(VII)的化合物是制备公式(I)的吡啶氧衍生物的有用中间体,例如,N-4-[4-(哌啶甲基)吡啶-2-氧基]-2-丁烯基}-2-(呋喃甲硫基)乙酰胺,其作为抗消化性溃疡剂很有用。 公式(VI)的化合物具有以下公式##STR1##其中A代表甲酰基,受保护的甲酰基,羟甲基或受保护的羟甲基。公式(VIII)的化合物具有以下公式##STR2##其中G代表甲酰基,受保护的甲酰基,羟甲基,受保护羟甲基,或卤代甲基,Y代表--CH.sub.2 --CH.sub.2 --或--CH.dbd.CH--,n为0、1或2。
