On December 20, 2012, Kawamura, Madoka; Kobashi, Yohei; Matsuda, Daisuke; Shiozawa, Fumiyasu; Suga, Yoichiro; Fusegi, Keiko; Kakinuma, Hiroyuki; Otake, Norikazu published a patent.Name: 2-Chloro-5-isopropylpyrimidine The title of the patent was Preparation of azaspiroalkane compounds as GPR119 agonists. And the patent contained the following:
Title compounds I [p = 0-2; q = 1 or 2; ring A = benzene ring or 6-membered heteroaryl; R11-R13 = independently H, halo, carbamoyl, etc.; X = -O- or -NR3-; R3 = H or alkyl; Y = alkanediyl; R2 = alkyl (optionally substituted with cycloalkyl or aryl), alkylsulfonyl, alkylcarbonyl, etc.; or pharmaceutically acceptable salts thereof], useful for the treatment of diabetes, were prepared For example, treatment of tert-Bu 2-(methoxymethylidene)-7-azaspiro[3.5]nonane-7-carboxylate (preparation given) with CF3CO2H/water, reaction with NaH/triethyl phosphonoacetate, hydrogenation, reduction using LiAlH4, reaction with 4-cyano-3-fluorophenol in the presence of N,N,N’,N’-tetramethylazodicarbamide, hydrolysis, and EDCI-mediated amidation with 2-aminoethanol afforded compound II. In GPR119 agonist activity test, EC50 of II was 9 nM. Pharmaceutical compositions comprising I are disclosed. The experimental process involved the reaction of 2-Chloro-5-isopropylpyrimidine(cas: 596114-50-0).Name: 2-Chloro-5-isopropylpyrimidine
