Abstract
A sulfonate derivative represented by the formula ##STR1## wherein R.sub.1 is lower alkyl, lower alkoxy or halogen, l is an integer of from 0 to 3, n is 0 or 1, A is straight-chain or branched-chain alkylene having 1 to 4 carbon atoms, and R.sub.2 is hydrogen or lower alkyl but, when n is 0 or 1 and A is straight-chain alkylene with 1 to 4 carbon atoms, is not hydrogen and the method for preparing the same.
Claims2
A sulfonate derivative represented by the formula ##STR60## wherein R.sub.1 is lower alkyl, lower alkoxy or halogen, l is an integer of from 0 to 3, n is 0 or 1, A is straight-chain or branched-chain alkylene having 1 to 4 carbon atoms, and R.sub.2 is hydrogen or lower alkyl but, when n is 0 or 1 and A is straight-chain alkylene with 1 to 4 carbon atoms, is not hydrogen.
An antilipemic composition comprising an effective amount of a sulfonate derivative represented by the formula ##STR61## wherein R.sub.1 is lower alkyl, lower alkoxy or halogen, l is an integer of from 0 to 3, n is 0 or 1, A is straight-chain or branched-chain alkylene having 1 to 4 carbon atoms, and R.sub.2 is hydrogen or lower alkyl but, when n is 0 or 1 and A is straight-chain alkylene with 1 to 4 carbon atoms, is not hydrogen and a pharmaceutically acceptable diluent.
