A series of (N-aryl)salicylaldimines was synthesized by the reaction of salicylaldehydes substituted in the positions 3 and 5 by bulky tert-butyl or α-cumyl groups with hydrochlorides of o-, m-, and p-(but-3-enyloxy) aniline in the presence of triethylamine. The obtained compounds formed by the reaction with TiCl2(OPr-i)2 complexes of titanium(IV) dichloride L2TiCl2.

Reaction of 5-methoxy-substituted salicylic aldehydes containing in the position 3 tert-butyl, 2-phenylpropan-2-yl, or 1-phenylethyl groups with m- and p-allyloxy-, (but-3-enyloxy)-, (pent-4-enyloxy)anilines without solvent in an open system at 130°C afforded a series of (N-aryl)salicylaldimines L that with TiCl2 (OPr-i)2 formed complexes of titanium(IV) dichloride L2TiCl2.

Discovery of the activating mutation V617F in Janus Kinase 2 (JAK2(V617F)), a tyrosine kinase critically involved in receptor signaling, recently ignited interest in JAK2 inhibitor therapy as a treatment for myelofibrosis (ME). Herein, we describe the design and synthesis of a series of small molecule 4-aryl-2-aminopyrimidine macrocycles and their biological evaluation against the JAK family of kinase enzymes and FLT3. The most promising leads were assessed for their in vitro ADME properties culminating in the discovery of 21c, a potent JAK2 (IC50 = 23 and 19 nM for JAK2(WT) and JAK2(V617F), respectively) and FLT3 (IC50 = 22 nM) inhibitor with selectivity against JAK1 and JAK3 (IC50 = 1280 and 520 nM, respectively). Further profiling of 21c in preclinical species and mouse xenograft and allograft models is described. Compound 21c (SB1518) was selected as a development candidate and progressed into clinical trials where it is currently in phase 2 for ME and lymphoma.
