<p>Method for preparing a compound (I): from the corresponding isothiazole amine and for example an ester, using a trialkyl-aluminium compound R?50R51R52¿AI where R?50, R51 and R52¿ are each independently C¿1-10? alkyl. The method is particularly suitable for use when the ester is base- and/or nucleophile-sensitive, especially when R?7¿ is an electron withdrawing group. Also provided is a trialkyl-aluminium intermediate compound formed during the method.</p> |
