Intermediate G2 To a solution of Intermediate G2 (806 mg, 2.97 mmol) and methyl 3-amino-5-methyl benzoate (490 mg, 2.97 mmol) in DMF (20 mL) was added p-TSA (1.13 g, 5.93 mmol) and the reaction mixture heated to 60C for 16 hr. After cooling to RT, the mixture was partitioned between EtOAc (30 mL) and saturated aq NaHC03 (30 mL). The organic phase was separated and was washed with water (30 mL) and brine (40 mL) and then dried and evaporated in vacuo. The residue was purified by flash column chromatography (Si02, 12.0 g, 0-100% EtOAc in isohexane, gradient elution) to afford the title compound, Intermediate 4, as a red oil (680 mg, 25%); R< 2.13 min (Method 2 acidic); m/z 401 (M+H)+, (ES+). |
