A novel 2-substituted-6,7-benzomorphan derivative of the formula: ##SPC1## And its acid addition salts, which are useful as non-addicting analgesics and antitussives and can be prepared by reacting a 2-unsubstituted-6,7-benzomorphan derivative of the formula: ##SPC2## With the reactive derivative of an alcohol of the formula: HOA', optionally followed by elimination of the protective group in the resulting product, wherein R.sub.1 is hydrogen, lower alkyl or acyl; R.sub.2 and R.sub.3 are each lower alkyl; A is lower alkyl, cyano(lower)alkyl, benzoyl(lower)alkyl, ar(lower)alkyl, lower alkenyl or cyclo(lower)alkyl(lower)alkyl; and A' is a group as mentioned in A or benzoyl(lower)alkyl of which the carbonyl group is masked with a suitable protective group.
