Reaction Steps

Combine (R)-N-[6-Acetyl-9-(3-fluoro-benzyl)-2,3,4,9-tetrahydro-1H-carbazol-3-yl]-isobutyramide (Example 191) (0.055 g, 0.14 mmol) and dimethylformamide dimethylacetal (0.81 g, 6.8 mmol) and heat at 100° C. for 82 h. Concentrate in vacuo and treat the resulting residue with hydroxylamine hydrochloride (0.012 g, 0.18 mmol) in dioxane at 23° C. for 1 h before warming to 40° C. briefly. Dilute with water and collect 0.029 g of a solid by filtration. Recrystallize from EtOAc/hexanes to yield a light yellow solid. mp: 238-241° C.; MS (ES): m/z 432 (M+1); HPLC: Rt=2.59 (85%).
