Procedure

To a solution of tert-butyl 4-(1-(3-(hydroxymethyl)-5-(trifluoromethyl)phenylcarbamoyl)-1H-indol-5-yloxy)-5,6-dihydropyrido[3,4-d]pyrimidine-7(8H)-carboxylate (0.211 g, 0.361 mmol) in 6 mL of DCM with DIEA (0.19 mL, 1.08 mmol) at 0° C., methanesulfonyl chloride (0.037 mL, 0.469 mmol) is added and the reaction stirred for 3 h. At that point the reaction is diluted with EtOAc, washed with saturated sodium bicarbonate, brine and the organic layer is dried over sodium sulfate. Concentration provides a mixture of the title compound and tert-butyl 4-(1-(3-(chloromethyl)-5-(trifluoromethyl)phenylcarbamoyl)-1H-indol-5-yloxy)-5,6-dihydropyrido[3,4-d]pyrimidine-7(8H)-carboxylate (3:7), which is carried on to next step.
