N-Unsubstituted 2,3-dihydro-1,4-diazepinium salts 4 a -d are N-methylated readily (-5ad) by using iodomethane and potassium carbonate in dimethylformamide. The 2,3dihydro-5,7-diphenyl-I ,4-diazcpinium salt 4 d could be N-ethylated but not N-isopropylated, presumably for steric reasons. Vicinal crowd
