Patent

CA 2591794

The invention relates to a process for preparing a compound of formula (IV) (see Formula IV) which comprises either reacting a compound of formula (VI) (see Formula VI) with a compound of formula R6X2 and subsequently reacting with a compound of formula QX1 to give a compound of formula IV in which n is 0, which can be converted to a compound of formula IV in which n is 1 or 2 by using an oxidising agent; or reacting a compound of formula (VII) (see Formula VII) with a compound of formula QX1 in order to obtain a compound of formula IV wherein n is 0, which can be converted with an oxidising agent to a compound of formula IV in which n is 1 or 2. The invention also relates intermediate compounds IV and VII and use of the compounds of formulae VI, VII and IV as intermediates.
