Reaction Steps

Through a solution of ethyl ((1S-5-{3-[(5-cyano-2-yridinyl)(propyl)amino]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (Example 265) (0.62 g, 1.47 mmol) in DMF (7 mL) at rt for 20 min was gently passed H2S. Diethylamine (0.23 mL, 2.21 mmol) was added in one portion, and the resultant light green solution was heated at 60° C. for 3 h. Upon completion of the reaction, the dark green solution was purged with a strong flow of argon, and then concentrated under reduced pressure. The product (0.63 g, 95%) was isolated after silica gel column chromatography (1:1 hexanes/EtOAc) as a yellow solid. 1H NMR (400 MHz, CD2Cl2) δ 8.68 (d, 1H), 8.02 (dd, 1H), 7.30 (b, 1H), 7.15-7.02 (m, 2H), 6.79 (d, 1H), 6.71 (dd, 1H), 6.49 (d, 1H), 4.16 (q, 2H), 4.00 (t, 2H), 3.75 (t, 2H), 3.56-3.45 (m, 3H), 2.96-2.78 (m, 2H), 2.75-2.68 (m, 1H), 2.48-2.34 (m, 2H), 2.11 (qt, 2H), 1.82-1.60 (m, 3H), 1.28 (t, 3H), 0.97 (t, 3H).
