Hydrochloric Acid → 2-[5-Chloro-2-(1-ethyl-5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide

Participants

Reaction Steps

Combined 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (82 mg, 0.276 mmol), 7-Amino-1-ethyl-5,5-dimethyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (61 mg, 0.263 mmol), 4 N HCl in dioxane (80 ul) and 2-methoxyethanol (3 mL). Heated reaction to 120° C. for 3.5 hours. Filtered off solid, then purified the solid with normal phase chromatography eluting with 9/1 methylene chloride/methanol. Washed product with saturated sodium bicarbonate solution and extracted into methylene chloride. Washed organic phase with brine, dried over magnesium sulfate, filtered and concentrated under reduced pressure to yield an off-white solid, 2-[5-Chloro-2-(1-ethyl-5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide (34 mg, 25%).
