Diisopropylcarbodiimide → 2,3-Diisopropyl-1-methyl-1-(3-(trimethoxysilyl)propyl)guanidine

Participants

Reaction Steps

A mixture of 60.5 g of N-methyl-(3-(trimethoxysilyl)propyl)amine (0.313 mol) and of 47.6 g of diisopropylcarbodiimide (0.376 mol, 20% excess) was heated for 3 h 30 min at 100° C. (amine conversion of greater than 99%). The final colorless mixture was devolatilized at 100° C. under 2 mbar for 2 h to give 99.5 g of a colorless, low-viscosity liquid corresponding to the expected guanidine.
