Procedure

A 1M solution of sodium cyanoborohydride in THF (0.15 mL, 0.15 mmol) was added to a solution of 13-cyclohexyl-N-(dimethylsulfamoyl)-3-methoxy-6-(3-oxa-7,10-diazatricyclo[3.3.3.01,5]undec-7-ylcarbonyl)-7H-indolo[2,1-a][2]benzazepine-10-carboxamide (Example 20) (10 mg, 0.015 mmol) and formaldehyde (37 wt. % in water) (0.01 mL, 0.1 mmol) in MeOH (1 mL) and the mixture was stirred at rt for 16 h. The reaction was filtered and purified by preparative HPLC (H2O-MeOH with 0.1% TFA buffer) to yield product 13-cyclohexyl-N-(dimethylsulfamoyl)-3-methoxy-6-((10-methyl-3-oxa-7,10-diazatricyclo[3.3.3.01,5]undec-7-yl)carbonyl)-7H-indolo[2,1-a][2]benzazepine-10-carboxamide (8.5 mg, 10 μmol, 68% yield) as a bright yellow solid.
