The present invention provides a process for the preparation of a compound of formula I [Chemical formula should be inserted here. Please see paper copy] in which a compound of formula II [Chemical formula should be inserted here. Please see paper copy] in which R is H or OR represents a protecting group for a carboxylic hydroxy group is reacted with a compound of formula III C6H13X wherein X is a leaving group, in the presence of a base in the presence of an inert solvent at a temperature in the range -25°C to 150°C and optionally, when OR represents a protecting group, removal of the protecting group.

Compounds of the formula STR1 wherein A is --CH2 --CH2 --, --CH=CH--, --NH--CO--, --CH2 --CO-- or STR2 where R7 is alkyl of 1 to 3 carbon atoms, and B is methylene, carbonyl or thiocarbonyl, or A is --CO--CO--, --N=CH--, STR3 where R8 is hydrogen or alkyl of 1 to 3 carbon atoms substituted by a phenyl, methoxyphenyl or dimethoxyphenyl, and B is methylene; E is n-alkylene of 2 to 4 carbon atoms optionally substituted by an alkyl of 1 to 3 carbon atoms, 2-hydroxy-n-propylene, 2-hydroxy-n-butylene or 3-hydroxy-n-butylene; G is n-alkylene of 1 to 5 carbon atoms optionally substituted by an alkyl of 1 to 3 carbon atoms, wherein one methylene group of an n-alkylene of 2 to 5 carbon atoms can be replaced by a carbonyl group, with the proviso that B represents a methylene or carbonyl group, or methylene-n-hydroxy-alkylene of 1 to 4 carbon atoms, where the methylene group is attached to the nitrogen atom; and R1 to R5 are simple substituents of various types; and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as their salts are useful as bradycardiacs.
