Procedure

1,1′-Thiocarbonyldiimidazole (5.74 g, 32.2 mmol) was added to a solution of N4-benzylquinoline-3,4-diamine, see U.S. Pat. No. 4,689,338 (Gerster), Example 124, Parts A and B, (6.69 g, 26.8 mmol) in pyridine (50 mL) and THF (50 mL), and the reaction was heated at 80° C. for two hours and cooled to room temperature. A precipitate was present and was isolated by filtration and washed with diethyl ether to provide 4.17 g of 1-benzyl-1H-imidazo[4,5-c]quinoline-2-thiol as a white solid. The filtrate was treated with diethyl ether, and additional precipitate formed. The precipitate was isolated by filtration and washed with diethyl ether to provide an additional 1.90 g of product as a pale yellow solid.
