Reaction Steps

In a flask containing 0.5 g (1.5 mmol) the product from Example 37A, 10 mL of pyrrolidine was added. After stirring at 80° C. for 3 h, the reaction mixture was concentrated under vacuum. The residue was diluted with 100 mL of CH2Cl2 and washed sequentially with water, sodium bicarbonate and brine, dried and evaporated under reduced pressure. Silica gel chromatography (MeOH:CH2Cl2, 95:5) gave the desired material in 98% yield. 1HNMR (300 MHz, CDCl3) δ 1.80 (m, 4H), 2.6 (m, 4H), 2.97 (t, 2H), 4.20 (t, 2H), 2.49 (m, 2H) 7.10–7.90 (m, 6H); MS (ESI) m/z 321 (M+H)+.
