| abstract | A process comprising reacting a 2-methyloxazoline of the formula ##STR1## in which R 1 , R 2 , R 3 and R 4 each independently is hydrogen, alkyl, aralkyl, optionally substituted aryl or two of them together form a ring, n with a 3-methyl-2-buten-1-yl derivative of the formula ##STR2## in which X is halide, sulphonate or phosphate, thereby to produce a 2-methyl-3-(3-methyl-2-butenyl)-2-oxazolinium salt of the formula ##STR3## reacting the oxazolinium salt with an alcoholate of the formula n n R.sup.5 --O--M (V) n n in which n M is one equivalent of an alkali metal or alkaline earth metal cation, n to produce an oxazolidine of the formula ##STR4## pyrolyzing the oxazolidine to produce a 2-methylene-3-(3-methyl-2-butenyl)-oxazolidine of the formula ##STR5## and heating the 2-methylene-3-(3-methyl-2-butenyl)-oxazolidine to produce a 2-(2,2-dimethyl-3-buten-1-yl)-2-oxazoline of the formula ##STR6## The compounds (II), (III) and (IV) are new. |
