Reaction Steps

Intermediate B1 (480 mg, 1.5 mmoles) was dissolved in CH3CN (7.5 mL). Solid K2CO3 (518 mg, 3.75 mmoles), solid KI (250 mg, 1.5 mmoles) and neat 4-fluoro-benzyl-bromide (0.191 mL, 1.5 mmoles) were added, and the mixture was heated in a sealed vial in a microwave oven at 120° C. for 30+30 minutes. The reaction mixture was diluted with water (40 mL) and extracted with AcOEt (3×40 mL). The organic layer was washed with brine, dried over Na2SO4, and evaporated to dryness. The crude was purified by flash chromatography (SiO2, petroleum ether/AcOEt from 9/1 to 7/3). The title compound was obtained as a light-yellow solid in amount of 407 mg.
