General procedure: Ethyl benzothiazole-2-carboxylate 4a (1 mmol) was taken in around bottom flask (10 mL). To it the aliphatic amine (4 equiv.) wasadded in excess along with (50 mg) of NH4Cl. The reaction mixturewas heated at 150 C for 2e3 h under magnetic stirring. Aftercompletion of reaction (TLC), the mixture was diluted using EtOAc,washed with1N HCl and brine, dried over anhydrous MgSO4 andconcentrated under reduced pressure to furnish the final productthat was then washed with cooled hexane.

To a 250 mL round bottom flask was added ethyl benzothiazole-2-carboxylate (1.0363 g, 5.0 mmol). 20 mL ethanol and 2 mL hydrazine hydrate were added followed by heating the solution to reflux for 6 hours. The reaction mixture was cooled to room temperature and solid precipitate was filtered, collected, and recrystallized in ethanol to yield benzo[d]thiazole-2-carbohydrazide (943.4 mg, 89.1% yield).

32137-76-1, Ethyl 1,3-benzothiazole-2-carboxylate is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 6Synthesis of benzothiazole-2-carboxamide (8)Benzothiazole-2-carboxamide was synthesized from ethyl benzothiazole-2-carboxylate according to the following reaction scheme. In particular, commercially available ethyl benzothiazole-2-carboxylate 6 (2.4 mmol, 0.5 g) was dissolved in 34 mL MeOH and purged with NH3 gas. Conversion to the product was monitored by TLC (3 Hexane: 2 EtOAc). Following complete conversion to the product 8 (30 min), the solvent was removed in vacuo. Agilent HPLC displayed 100% conversion to the desired product 8 with a single peak at 8.0 min. The solid white compound was used in the subsequent step without purification. ESI-MS: m/z calcd for C8H6N2OS 179.02 (M+H)+, 179.88 found (100%) (see LC/MS spectra of FIG. 17A and NMR spectra of FIG. 17B)., 32137-76-1
