该中间体在本合成路线中的序号：(XXVIII)In a further method, Mannich reaction of 4,4-dimethylcyclohexanone (XVII) with tert-butyl 4-piperazinobenzoate (XXVIII) and paraformaldehyde by means of HCl in tert-butanol affords the piperazinylmethyl-cyclohexanone (XXIX), which is further condensed with 4-chlorophenylmagnesium bromide (XXX), yielding carbinol (XXXI). Simultaneous dehydration of alcohol (XXXI) and cleavage of the tert-butyl ester in refluxing 6 M HCl gives carboxylic acid (IX) (3). Scheme 4.
