Reaction Steps

2-Chloro-7,7-difluoro-5-methyl-9-((3R)-3-methylcyclopentyl)-8,9-dihydro-5H-pyrimido[4,5-b][1,4]diazepin-6(7H)-one (500 mg, 1.51 mmol) and 4-amino-3-methoxybenzoic acid (316.0 mg, 1.89 mmol) were weighed into a flask. 4-Methylbenzenesulfonic acid monohydrate (230.0 mg, 1.21 mmol) was weighed into a separate flask and dissolved in dioxane (15 ml). The toxic acid solution was then added to the flask containing the two starting materials. The reaction was stirred at 85° C. for 48 hours followed by 100° C. for an additional 48 hours. The dark brown mixture was cooled to room temperature and filtered through paper. The solids were washed with ethyl acetate (15 ml). m/z 462.4 (M+H)+.
