Reaction Steps

150 mg (0.3 mmol) of compound 3-(2,4-dichlorophenyl)-6-[2-(hydroxymethyl)-1,3-thiazol-4-yl]-1,9-dimethyl-1,9-dihydro-2H-pyrido[2,3-b]indol-2-one from Example 9 above are dissolved in 10 ml of DMF. 50 mg of 60% NaH (0.96 mmol) are added and the mixture is stirred at ambient temperature for 30 min. 0.05 ml (0.6 mmol) of cyclopropyl bromide are added and the mixture is then stirred at ambient temperature for 3 hours. Water is added and the mixture is extracted with EtOAc. The product is washed with a saturated NaCl solution followed by adsorption onto silica. Purification is carried out by chromatography on a silica column, elution being carried out with EtOAc.
