Reaction Steps

2-Fluoro-N-[3-(1-methyl-pyrrolidin-2-ylmethoxy)-4-trifluoromethyl-phenyl]-nicotinamide (402 mg, 1.0116 mmol) was dissolved in tert-butanol (1 mL). To this mix was added TFA (115 mg, 1.0116 mmol) and 4-amino-2,3-dihydro-isoindol-1-one (450 mg, 3.035 mmol). The mix was heated for 6 h at 150° C., allowing the solvent to boil off. The reaction was cooled to RT, dissolved into 1N aqueous HCl, basified to pH 10 with solid NaOH, extracted twice with EtOAc, and dried over Na2SO4. The product precipitated out of solution along with a minor by-product. The EtOAc was filtered off. The crude product was dissolved in MeOH and filtered. The MeOH solution was concentrated down and eluted on silica gel column to yield the titled compound as a light yellow solid. MS: C27H26F3N5O3—525.528; M+H 526.1
