Procedure
11.8 g (0.1 mole) 2-methyl-4-chloro-2-butenal is dripped at ambient temperature into a solution of 10.4 g (0.13 mole) of potassium methylate in 60 ml of methanol and the whole is stirred for an hour. The product is worked up as described in Example 1. 10.5 g of 2-methyl-4,4-dimethoxybutanal is obtained by distillation at subatmospheric pressure. According to gas chromatographic and nmr analysis it has a purity of more than 98%. The yield is 72% of theory.
