Participants

Reaction Steps

To a solution of 3-(2-chloro-5-fluoro-pyrimidin-4-ylamino)-propan-1-ol (Example 80, 0.66 g, 3.20 mmol) and 2-(5-hydroxy-indol-1-yl)-propionic acid methyl ester (Example 7, 0.47 g, 2.13 mmol) in dichloromethane (10.80 mL) was added triphenylphosphine (0.85 g, 3.20 mmol) and 1,1′-(azodicarbonyl)-dipiperidine (0.82 g, 3.20 mmol) under argon. The golden yellow mixture was stirred at rt for 18 h. The desired product (0.54 g, 59%) was obtained after column chromatography (67% hexanes in EtOAc). 1H NMR (300 MHz, CD3OD) δ 7.85 (d, 1H), 7.27-7.06 (m, 3H), 6.82-6.79 (m, 1H), 6.40 (d, 1H), 5.24 (q, 1H), 4.11-4.07 (m, 2H), 3.70-3.67 (m, 5H), 2.15-2.09 (m, 2H), 1.77 (d, 3H).
