An intramolecular thermal cyclization protocol was developed in a flow reactor to take advantage of the high pressures and temperatures that are easily obtained in small scale autoclave reactors that have been modified to handle slurries. This reactor was equipped with a fill/empty pumping system to enable easy and nearly complete transfer of slurries. The reaction conditions were designed to take advantage of the insolubility of the product in order to separate it from residual starting material by filtration after short reaction times. Recycling of the filtrate maximized the yield and throughput while minimizing decomposition. Recycles were accomplished using a strip to dryness protocol that was easily performed in a rotary evaporator. This new equipment set was designed with lab-hood manufacturing in mind, a minimized footprint, and the system was completely automated for charging, emptying, rinsing, and reacting. Additional efforts for quick screening and alternate modes of addition were also investigated.

A series of novel quinoline-3-carboxamide derivatives were synthesized and evaluated for their immunomodulatory activity. The compounds were tested in vitro for effects on spleen lymphocyte proliferation and TNF-α production by macrophage. Three compounds showed immunomodulatory profiles similar to and more potent than those of linomide and FR137316 and were selected for further pharmacological studies in vivo.
