The present disclosure is concerned with certain pyrrolopyrimidine compounds that are capable of inhibiting certain protein kinases, and especially the leucine-rich repeat kinase 2 (LRRK2) protein. Compounds of the present disclosure can be used to treat a number of disorders caused by or associated with abnormal LRRK2 kinase activity. Compounds of the present disclosure can be used to treat disorders including neurodegenerative diseases such as Parkinson's disease; precancerous conditions and cancer; autoimmune disorders such as Crohn's disease, rheumatoid arthritis and psoriasis; and leprosy (Hansen's disease). This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

A one-pot process for preparing 2,6-diaminopurine derivatives or an acid addition salt thereof comprising: (i) reacting a purine compound with an amine compound in the presence of a tertiary amine at a pH of 7 to 14 to form a 6-substituted aminopurine derivative, and (ii) reacting the 6-substituted aminopurine with an aromatic amine in the presence of an acid catalyst at a pH of 0.1 to less than 7.
A practical synthesis of N-[4-(6-cyclobutylamino-9H-purin-2-ylamino)-phenyl]-N-methyl acetamide (QAB205, 5a), an antiasthmatic agent, is described from 2,6-dichloropurine (1) by base-assisted substitution of the 6-chloro substituent with cyclobutylamine (2a) followed by a new trimethylsilyl chloride-catalyzed displacement of the 2-chloro group in intermediate 6-cycbutylamino-2-chloropurine (3a) with
N²-quinoline or isoquinoline substituted purine derivatives
