On August 16, 2001, Fotouhi, Nader; Gillespie, Paul; Guthrie, Robert William; Pietranico-Cole, Sherrie Lynn; Yun, Weiya published a patent.Synthetic Route of 19989-66-3 The title of the patent was Preparation of N-aroyldehydroamino acids as lymphocyte function associated antigen-1 antagonists.. And the patent contained the following:

Title compounds [I; R1 = H, OH, amino, halo; R2 = H, OH, halo; R3 = H; R2R3 = atoms to form Ph, pyrrole, pyrroline, pyrazole, triazole, imidazole, etc., rings; A = CH2CH2CH(OH), CH2CH2CO, CH2NHCO, etc.; R4, R5 = H, Me, Et; B = H, alkyl, (substituted) (bicyclic) (hetero)aryl, etc.; R6 = CO2H, CO2R7, CH2OH, etc.; R7 = alkyl, dimethylaminoalkyl, pyrrolidinylalkyl, etc.], were prepared Thus, Me (Z)-3-(1H-benzotriazol-5-yl)-2-[[2-chloro-4-[[(3-hydroxybenzyl)amino]carbonyl]-6-methylbenzoyl]amino]propenoate (preparation given) was stirred 125 h with LiOH in MeOH/THF/H2O to give 61% (Z)-3-(1H-benzotriazol-5-yl)-2-[[2-chloro-4-[[(3-hydroxybenzyl)amino]carbonyl]-6-methylbenzoyl]amino]propenoic acid. The latter inhibited LFA-1 binding to immobilized ICAM-1 with IC50 = 0.4 nM. The experimental process involved the reaction of Benzo[d]thiazol-6-ylmethanol(cas: 19989-66-3).Synthetic Route of 19989-66-3
