چکیده
The reaction of 3-amino-5-bromo-pyridine with N-iodo-succinimide in the presence of acetic acid produces the title compound, C(5)H(4)BrIN, with an iodo substituent in position 2 of the pyridine ring. The crystal structure features rather weak inter-molecular N-H⋯N hydrogen bonds linking the mol-ecules into chains along the z axis of the crystal.

2-(2-Cyano-2-phenylethyl)aziridines were converted into novel cis- and trans-2-chloromethyl-4-phenylpiperidine-4-carbonitriles via alkylation with 1-bromo-2-chloroethane followed by microwave-assisted 6-exo-tet cyclization and regiospecific ring opening. The latter piperidines were used as eligible substrates for the synthesis of stereodefined 2-chloromethyl-, 2-hydroxymethyl-, and 2-carboxymet...
