Why am I getting E2029 Declaration expected but 'FINALIZATION' found

I don't see any syntax error, my code compiles clean without the finalization section. Here is the last few lines of the unit.

function boolAsTF(b:boolean): string; inline;
begin
  if b then result := 'T' else result := 'F';
end;

finalization
  SyncMgr.Free;
end.
