Compounds of the formula I ##STR1## where R.sup.1 is hydrogen, lower alkyl, lower alkoxy, amino or dialkylamino; R.sup.2 and R.sup.3 are O-alkyl, N-dialkyl or S-alkyl, or R.sup.2 and R.sup.3 together represent --X--(CH.sub.2).sub.m --X, a carbonyl group or an imino group NR, and m is 2-6; where R.sup.4 is lower alkyl, cycloalkyl, alkenyl or dialkylamino, and where R.sup.5 is lower alkyl or cycloalkyl, and where n is 1 or 2, have excellent cytoprotective effects. They are prepared by reacting compounds II ##STR2## with formaldehyde or a reagent producing formaldehyde.
