Protecting-group-free synthesis of a dual CCK1/CCK2 receptor antagonist

In our pursuit of an efficient, protecting-group-free synthesis of the dual CCK1/CCK2 receptor antagonist 1, we have developed chemoselective conditions for sulfonamide formation reaction in pure water and a PhNMe2 mediated carboxamide formatio
