N-(3-trimethoxysilylpropyl)butan-1-amine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 45 g of N-butyl-(3-(trimethoxysilyl)propyl)amine (0.191 mol) and of 28.95 g of diisopropylcarbodiimide (0.229 mol, 20% excess) was heated for 20 h at 120° C. (amine conversion of 93%). The final colorless mixture was devolatilized at 120° C. under 1 mbar for 2 h to give 67 g of a colorless, low-viscosity liquid corresponding to the expected guanidine, containing 4 wt % of the initial amine.
