Reaction Steps

3-(1-Aminoethyl)-8-chloro-2-phenylisoquinolin-1(2H)-one (Compound 9) and 6-chloro-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (Compound 4) are combined in the presence of triethylamine and isopropyl alcohol. The reaction solution is heated at 82° C. for 24 hours to afford Compound 10. The intermediate compound 10 is treated with concentrated HCl and ethanol under aqueous conditions at 35° C. to remove the tetrahydropyranyl group to yield (S)-3-(1-(9H-purin-6-ylamino)ethyl)-8-chloro-2-phenylisoquinolin-1(2H)-one. Isolation/purification under aqueous conditions affords polymorph Form C.
