Procedure

Prepared according to the method of example 98 (b), using N-[6-chloro-2-[(3R)-3-cyano-1-pyrrolidinyl]-5-quinolinyl]-cyclohexaneacetamide (example 100 (a)) (66 mg), dibutyltin oxide (9 mg) and azidotrimethylsilane (0.06 mL). The residue was purified by ion exchange column (Varian NH2 cartridge, methanol then 3% acetic acid in methanol as eluant). Further purification by ion exchange column (Varian SCX cartridge, methanol then 7N ammonia in methanol as eluant) gave the title compound as a solid (11 mg).
