Procedure

To a solution of methyl 14-cyclohexyl-3-fluoro-5,6,7,8-tetrahydroindolo[2,1-a][2,5]benzodiazocine-11-carboxylate (from Step 5) in DCM (0.15 M), DIPEA (4 eq.), dimethylglycine (3 eq.) and HATU (2 eq.) were added and the mixture stirred at RT overnight. The solution was diluted with DCM and HCl (1N) and the 2 phases separated. The aqueous phase was extracted with DCM (twice). The combined organic phases were then washed with a saturated aqueous solution of NaHCO3 and brine before being dried (Na2SO4), filtered and concentrated in vacuo. The crude was used in the next step without further purification; MS (ES+) m/z 492 (M+H)+.
