  The present invention discloses an improved and novel process for the preparation of erlotinib (N-(3-ethynylphenyl)-6,7-bis(2-methoxyethoxy)-4-quinazolinamine) of formula (1), which comprises: (i) demethylation of commercially available 6,7-dimethoxy-4(3H)-quinazolinone of formula (8); acetylation using acetic anhydride; (iii) introduction of a leaving group at C-4 position in quinazolinone; (iv) condensation with 3-ethynylaniline to get novel compound of formula (12); (v) deacetylation to get novel dihydroxy compound of formula (13); and (vi) O-alkylation with 2-iodoethylmethyl ether to get the erlotinib base of formula (1). Erlotinib base is purified by recrystallization from ethyl acetate to get a HPLC purity of >99.5%. Salt formation of this base with hydrogen chloride gave pharmaceutically acceptable erlotinib hydrochloride of formula (1 a ) with a HPLC purity of >99.8%. Erlotinib hydrochloride is useful for the treatment of proliferative disorders, such as cancers, in humans.

• Synthesis and Evaluation of Novel Erlotinib–NSAID Conjugates as More Comprehensive Anticancer Agents

  A series of novel anticancer agents were designed and synthesized based on coupling of different nonsteroidal anti-inflammatory drugs (NSAIDs) with the epidermal growth-factor receptor (EGFR) tyrosine kinase inhibitor, erlotinib. Both the antiproliferative and pharmacokinetic activity of the target compounds were evaluated using HCC827 and A431 tumor cell lines. Among the derivatives made, compounds 10a, 10c, and 21g showed superb potency, comparable to that of erlotinib. Furthermore, preliminary SAR analysis showed that when the NSAIDs were conjugated via linkage to C-6 OH versus linkage to C-7 OH of the quinazoline nucleus, superior anticancer activity was achieved. Finally, the in vitro pharmacokinetic profile of several conjugates demonstrated the desired dissociation kinetics as the coupled molecules were effectively hydrolyzed, releasing both erlotinib and the specific NSAID in a time-dependent manner. The conjugation strategy represents a unique and simplified approach toward combination therapy, particularly for the treatment of cancers where both EGFR overexpression and inflammation play a direct role in disease progression.
