摘要

1-(2-Cyano-5-methylphenoxy)-2-hydroxy-3-alkylaminopropanes. (I):- (where R is 2-6C alkyl, pref. t. butyl are used for treating coronary conditions, tachycardia and hypertonia. They are prepd. e.g. from an epoxypropane or halohydrin and NH2R or RNHCONHR or by introducing the alkyl into the unsubstd. amine or by removing an easily hydrolysable gp. G from -OCH2 HCH2NHR or by removing protective gp. P from -OCH2 HCH2 R or by hydrolysing an oxazolidinone or by diazotising an 2-aminomethylphenoxy cpd. to the 2-cyano- cpd.
