Versuchsvorschrift

DMF (1 drop) was added to a solution of 2,2-bis(chloromethyl)propanoic acid (1.4 g) in DCM (1.5 ml), the solution was cooled to 0° C. and oxalyl chloride (0.75 ml) added. After gas evolution had stopped the mixture was concentrated in vacuo to give the sub-title compound as a yellow oil (1.51 g) which was used directly in the next step.
