Compounds 1221 were subjected to tyrosinase inhibition studies and SAR studies were carried out. This study reflected that the inhibition was enhanced with increase of carbon chain. In case of the compound 17, the OH group was replaced with CH2CH2OH with a resulting increase in inhibition against tyrosinase. The result of this work is that the E-factor for the process is very low with just 6 Kg of waste per kilogram of product compared with an industry average of 25100 Kg. In contrast, conventional heating failed to produce similar results, even after prolonged heating. Compound 10, upon chlorosulfonation followed by the coupling of various nucleophiles, yielded a series of compounds 1220 as analogs of sildenafil ( 21 ).

Pfizer received the 2003 UK Award for Green Chemical Technology (Best Process category) for the sildenafil citrate process. From Altmetric Log in (Free Access).

Compound 17 was found to be more potent than the potent reference inhibitor LM and KA. The 2D and 3D hydrogen bonding descriptors that help to study QSPR were also calculated.

Compound 7 was synthesized by the bromination followed by the amidation of readily available 1-methyl-3-propyl-1. H -pyrazole-5-carboxylic acid ( 5 ). Compounds 9 and 10 were obtained as SNAr reaction products, apparently through the proposed dipolar high-energy transition states TS-1 and TS-2 under MW irradiation, respectively.
