Procedure

According to still another embodiment (Scheme 3) the (S)-4-fluoromethyl-dihydro-furan-2-one is directly coupled with the amino-pyrido[2,1-a]isoquinoline derivative (VIII) to form the hydroxymethyl derivative of the pyrido[2,1-a]isoquinoline (XI), which is subsequently cyclisized to the fluoromethyl-pyrrolidin-2-one derivative (IX). The latter can be deprotected to yield the desired pyrido[2,1-a]isoquinoline derivative (II).
