2. An alternative route has also been applied to obtain compound VIIa. p-Methoxybenzyl 3-oxo-9-carbomethoxy-pelargonate was transformed via its 2-chloro-derivative into p-methoxybenzyl 4-(6-carbomethoxyhexyl)-thiazole-5-carboxylate, which afforded, upon treatment with trifluoroacetic acid at 25°, compound VIIa.
