(2,2-dimethylcyclopropyl)boronic acid

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a degazed solution of 2-amino-6-bromobenzonitrile (851 mmol, 168 mg), 2,2-dimethylcyclopropylboronic acid (1.106 μmol, 126 mg) (Example 270b), and Cs2CO3 (2.979 mmol, 970 mg) in DME (3.4 mL) and water (850 μL) was added tetrakis(triphenylphosphino)palladium(0) (43 μmol, 50 mg) under nitrogen and the reaction mixture microwaved for 2 hours at 160° C. The reaction mixture was cooled to room temperature and extracted with EtOAc (3×5 mL). The combined organic layers was washed once with brine (5 mL), dried over sodium sulfate, filtered and evaporated. The crude product was purified on silica gel (EtOAc/hexanes 10%-40%) to give the desired product (71 mg, 45%) as a waxy, yellow solid. 1H NMR (400 MHz, CDCl3) δ 0.82 (m, 1H), 0.82 (s, 3H), 0.85 (m, 1H), 1.33 (s, 3H), 1.92 (m, 1H), 4.36 (br. s, 2H), 6.47 (d, J=8 Hz, 1H), 6.56 (d, J=8 Hz, 1H), 7.20 (t, J=8 Hz, 1H). the reaction mixture microwaved for 2 hours at 160° C extracted with EtOAc (3×5 mL) The combined organic layers was washed once with brine (5 mL) dried over sodium sulfate filtered evaporated The crude product was purified on silica gel (EtOAc/hexanes 10%-40%)
