## Abstract A useful synthetic approach to carbon‐11 labelled 1,4‐dihydropyridines is described. Carbon‐11 labelled calcium channel antagonists ^11^C‐Nifedipine, ^11^C‐Nisoldipine, ^11^C‐Nitrendipine and ^11^C‐CF~3~‐Nifedipine were synthesized by a modified Hantzsch method using protected carboxy f
