Procedure

A mixture of (R)-indan-1-yl-(5-iodo-quinolin-2-yl)-amine (example 1, step A) (1.44 g, 3.73 mmol), zinc cyanide (482 mg, 4.1 mmol) and tetrakis-(triphenylphosphine)-palladium (431 mg, 0.37 mmol) in dimethylformamide (20 ml) was heated at 160° C. for 15 min in a microwave reactor. The reaction mixture was poured into water (50 ml) and extracted with ethyl acetate (2×100 ml). The combined organic layers were washed with brine (50 ml), dried (MgSO4) and evaporated. The crude product was purified by flash chromatography (ethyl acetate/heptane) on silica gel and crystallization (diethyl ether/hexane) to yield 2-((R)-indan-1-ylamino)-quinoline-5-carbonitrile as light yellow solid (840 mg, 79%). M.p. 150° C.; MS: m/e=286.2 (M+H+).
