With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.134676-67-8,N-Boc-2-thiomorpholinecarboxylic Acid,as a common compound, the synthetic route is as follows.
Step 1 (+/-)-4-tert-butoxycarbonyl-N-(9-chloro-3,4-dihydro-2H-l,5-benzodioxepin- 7-ylmethyl)-N-isobutyl thiomorpholine-2-carboxamide: The mixture of N-(9-chloro-3,4- dihydro-2H- 1 ,5-benzodioxepin-7-ylmethyl)-2-methylpropan- 1 -amine (150 mg), thiomorpholine-2,4-dicarboxylic acid 4-tert-butyl ester (137 mg), l-ethyl-3-(3- dimethylaminopropyl)carbodiimide hydrochloride (138 mg), and dimethyl aminopyridine (92 mg) in dichloromethane (15 ml) was stirred at room temperature overnight. After the addition of water (10 ml), the mixture was extracted with 10 ml ethyl acetate three times. The organic layer was washed with saturated sodium bicarbonate, water and brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude was purified by column chromatography on silica (20-33% ethyl acetate in hexane) to give the desired product as a resin: MS (m+l) = 499.4.
The synthetic route of 134676-67-8 has been constantly updated, and we look forward to future research findings.
