With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3364-80-5,Thiazole-4-carboxaldehyde,as a common compound, the synthetic route is as follows.

A stirred mixture of 2-amino-4-methyl-pentanoic acid tert-butyl ester, hydrochloride (2. 1G, 9.38 mmol), 1, 3-thiazole-4-carboxaldehyde (Intermediate b) (1. 06 g, 9.38 MMOL) and triethylamine (1.31 mL, 9.38 MMOL) in dichloromethane (25 mL) was heated under reflux under nitrogen for 20 hours. The reaction mixture was allowed to cool to room temperature, washed twice with water, dried over NA2SO4 and evaporated to give the title compound as an oil. ‘H NMR (CDCI3) : 5 8.84 (s, 1H), 8.49 (d, 1 H), 8.01 (s, 1H), 4.00 (dd, 1 H), 1.90-1. 70 (m, 2H), 1.64-1. 56 (m, 1H), 1.47 (s, 9H), 0.96 (d, 3H) and 0.91 (d, 3H)., 3364-80-5

[623] Example 158 – 3-ri-Methyl-5-(4-methyl-cvclohexyl)-l,2,3,6-tetrahydro-pyridin-4-yl1-5-r4-; [624] A mixture of 4-bromobenzyl bromide (1.00 g, 4.00 mmol) and triphenylphosphine (1.70 g, 6.00 mmol) in toluene (10 mL) was stirred at 80 ¡ãC overnight. The reaction mixture wasconcentrated, followed by sonication in hexane, filtration, and a subsequent hexane wash gave a white solid, which was dried in vacuo. This white solid (906 mg, 1.77 mmol) was dissolved in THF (10 mL), cooled to 0 ¡ãC, and lithium hexamethyl disilazide (1 M) in THF (1.95 mL, 1.95 mmol) was added. After 0.5 hr, thiazole-4-carboxaldehyde (200 mg, 1.77 mmol) was added, the ice bath was removed, and the mixture stirred for 0.5 hr. The reaction mixture was quenched by the addition of water, extracted with EtOAc (2×30 mL), the organic layer was washed with brine, dried over MgS04, concentrated and filtered through a silica plug using 30percent -100percent EtOAc/hexane to give 158A as a clear oil. MS calcd: M+H)+ = 267. + = 267.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3364-80-5,Thiazole-4-carboxaldehyde,as a common compound, the synthetic route is as follows.

General procedure: A solution of substituted o-phenyldiamine (1.0 equiv), thiazole-4-aldehyde or pyridine-2-aldehyde (1.0 equiv) with sodium pyrosulfite in DMF was stirred at 120¡ã C overnight. On completion of the reaction monitored by TLC, the solvent was evaporated and the residue was purified by silica gel chromatography by DCM/MeOH system to afford the final product. If necessary, the crudeproduct could be recrystallized in DCM or dichloroethane to afford pure sample.
