Versuchsvorschrift

The title compound from Step 1 (5.0 g, 17.5 mmol), 2-bromo-1-(cyclopropylmethoxy)-4-methylsulfonylbenzene (6.4 g, 21 mmol), K3PO4 (9.3 g, 43.9 mmol) and Pd(dppf)Cl2 (1.4 g, 1.75 mmol) in a dioxane/water (100 mL/10 mL) mixture were stirred at 60° C. for 12 hrs. The reaction mixture was concentrated under reduced pressure and the residue was purified by column chromatography on silica gel (EA: DCM=1:4). Appropriate fractions were combined and concentrated under reduce pressure. The resultant solid was recrystallized from DCM/MTBE (1:1, 50 mL) to give the title compound (4.0 g, 60%) as a white solid. 1H NMR: (CDCl3, 400 MHz) δ 8.51 (dd, J1=8.0 Hz, J2=0.8 Hz, 1H), 7.98 (dd, J1=8.4 Hz, J2=2.4 Hz, 1H), 7.86 (d, J=2.4 Hz, 1H), 7.53 (m, 2H), 7.16 (d, J=7.6 Hz, 1H), 7.10 (m, 2H), 3.88 (m, 2H), 3.66 (s, 3H), 3.09 (s, 3H), 1.02-0.98 (m, 1H), 0.44-0.38 (m, 2H), 0.11-0.09 (m, 2H). LCMS: 384.1 (M+H)+
