The 2-benzyl-4,4-dimethyl-1-pyrroline of the formula III is then cyclized with ω-bromo-4-chloroacetophenone to give the 6-(4-chlorophenyl)-2,2-dimethyl-7-phenyl-2,3-dihydro-1H-pyrrolizine of the formula II. The reaction is known from the prior art mentioned at the outset. ω-Bromo-4-chloroacetophenone can be obtained, for example, as described in Bull. Soc. Chim. Fr. 21, 69 (1899).
