Sodium hydride → HCID 19956392, compound

Participants

Reaction Steps

To a solution of 0.7 g (1.092 mmol) of (E)-1-allyl-1,5,10,14-tetra-BOC-1,5,10,14-tetraazatetradec-7-ene (see Example 2a) in 9.4 ml of DMF there are added, with stirring, 0.087 g (2.175 mmol) of sodium hydride dispersion (approx. 60%) and, after 5 min., 0.212 ml (2.176 mmol) of propyl iodide. The reaction mixture is stirred for 15 h at room temperature; a further 0.043 g (1.075 mmol) of sodium hydride dispersion (approx. 60%) and 0.106 ml (1.088 mmol) of propyl iodide are added, and the mixture is stirred for a further 96 h at 20° C. and is then concentrated by evaporation in vacuo. Working up analogously to Example 1a) yields the oily title compound, Rf value=0.46 (silica gel/ethyl acetate:hexane (2:3)).
