2-Methyl-2-propanyl 1H-spiro[isoquinoline-4,4'-piperidine]-2(3H)-carboxylate hydrochloride (1:1)(CAS: 889139-52-0)

This compound is a crystalline solid with a molecular weight of approximately 346.37 g/mol. It is slightly soluble in water and has a pKa of around 3.5. It is reactive towards bases and can undergo hydrolysis under basic conditions.

This compound is usually synthesized via a multistep process involving the coupling of 2-methyl-2-propanol with 4-(3-bromopropyl)-4'-methylpiperidine, followed by condensation with an isatin derivative. The reaction is catalyzed by a suitable base and proceeds with high selectivity, yielding a product with a purity of over 95%.

This compound is primarily used in the pharmaceutical industry for its potential as a drug precursor. It is also of interest in the development of advanced functional materials, including polymers and sensors, due to its unique chemical structure and reactivity.

Handling this compound requires the use of personal protective equipment (PPE) including gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and other strong oxidizing agents. Spills should be handled in a fume hood with appropriate safety measures, and proper safety data sheets (SDS) should be consulted for detailed procedures.
