Abstract
Processes and intermediates for preparing 1-alkylamino-3-(5-substitutedaminocarbonylthiazol-2-yloxy)-2-propanols and 5-(5-substitutedaminocarbonylthiazol-2-yloxymethylene)-N-alkyloxazolidine and 2-substituted oxazolidine derivatives thereof and intermediates therefore. The present processes, and intermediates, reduce the number of transformations necessary to produce these products as compared with the prior processes. The products are useful to treat abnormal heart conditions and/or hypertension in mammals. The intermediates are 2-alkylsulfinyl-5-substitutedaminocarbonylthiazoles and 2-alkylsulfonyl-5-substitutedaminocarbonylthiazoles.
