To a solution of 3-[(2-chloro-5-methyl-4-pyrimidinyl)(methyl)amino]-1-propanol (0.316 g, 1.47 mmol) (prepared in similar fashion as Example 83) and 5-hydroxyindole (0.195 g, 1.47 mmol) in dichloromethane (7 mL) was added triphenylphosphine (1.15 g, 4.40 mmol) and 1,1′-(azodicarbonyl)-dipiperidine (1.11 g, 4.40 mmol) under argon. The golden yellow mixture was stirred at rt for 24 h. The desired product (0.117 g, 24%) was obtained after column chromatography (50% hexanes in EtOAc). LC/MS m/z 331.3 (M+H)+, RT 2.76 min.
