Oxyphencyclimine is an antimuscarinic.

Synthesis

Reaction of chloroacetonitrile (1) with methanol and hydrogen chloride leads to the corresponding iminoether (Pinner reaction). Condensation of 2 with 3-methylaminopropylamine gives (3) gives the corresponding tetrahydropyrimidine (4). Displacement of the halogen with the sodium salt 5 affords oxyphencyclimine (6).

Oxyphencyclimine synthesis:[1] GB 795758  (1958 to Pfizer).
