Participants

Reaction Steps

209 mg (0.49 mmol) of compound from Example 47, 3-(2,4-dichlorophenyl)-1,9-dimethyl-6-(1H-[1,2,3]triazol-4-yl)-1,9-dihydropyrido[2,3-b]indol-2-one, are dissolved in 3 ml of DMF. 30 mg (0.74 mmol) of 60% NaH and a spatula tip of dibenzo-18-crown-6 are added. 80 μl of bromomethyl methyl ether are then added. The mixture is stirred at ambient temperature for 16 hours. The reaction medium is poured into water and then extracted with EtOAc and the organic phase is dried over MgSO4, filtered and evaporated to dryness, adsorbing onto silica. Purification is carried out on a silica column, elution being carried out with a gradient of EtOAc/50% cyclohexane, then with EtOAc/40% cyclohexane and, finally, 100% EtOAc. The residue is triturated in MeOH so as to obtain a beige solid.
