Abstract Reductive cyclization of 2-N-[(2-amino-4,6-dichloropyrimidin-5-yl)methyl]-N-phenethylamino}acetonitrile (5) with Raney nickel and hydrogen gave the chloropyrimido[4,5-e][1,4]diazepine 3 which could not be converted to 2 via an attempted nucleophilic aromatic substitution with hydroxide. The title compound (2) was prepared, however, by the reductive cyclization of 2-N-[(2-amino-4-chloro-
