4-(2,3-Epoxypropoxy)salicylic acid methyl ester → 1-[N-[2-(3-carbamoyl-4-hydroxyphenoxy)-1-methylethyl]benzylamino]-3-(3-hydroxy-4-methoxycarbonylphenoxy)propan-2-ol

Participants

Reaction Steps

After 40 hours' boiling and working up analogously to Example (4a), 22.4 g of 4-(2,3-epoxypropoxy)salicylic acid methyl ester and 30 g of 5-(2-benzylaminopropoxy)-salicylamide in 200 ml of isopropanol yield crude 1-[N-[2-(3-carbamoyl-4-hydroxyphenoxy)-1-methylethyl]benzylamino]-3-(3-hydroxy-4-methoxycarbonylphenoxy)propan-2-ol as a light-coloured foam which is further processed as a crude product.
