PROCESS FOR THE PREPARATION OF ALKANOLAMINE DERIVATIVES

摘要

Title compds. (I; R1 = C1-6 alkyl; R2 = C1-3 alkyl; R3 = H, halogen, C1-3 alkyl; n = 1 or 2), useful as β-sympatholytics(no data), were prepd. by reaction of II and R1NH2. Thus, trans-II(R3 = Me) was refluxed with Me2CHNH2 for 16 hr to give erythro-I(R2 = Me; R1 = Me2CH; R3 = Me, n = 1). Treatment of 7-methylindan-4-ol with MeCH:CHCOCl followed by oxidn. with H2O2 gave II(R3 = Me).
