The 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).
