The synthetic route is as follows., SDS of cas: 1914-02-9

A mixture of 3,3-dimethylindoline (103 mg, 0.700 mmol), potassium carbonate (288 mg, 2.084 mmol), and 2-bromopropanenitrile (303 mu^, 3.506 mmol) in 2 mL CH3CN was stirred at 80C (oil bath) over night. The mixture was purified by preparative HPLC. Fractions containing product were partly concentrated and residue was extracted with 1 M NaHC03and CH2C12. Organic phases were dried over MgS04, filtered, and concentrated to give 2-(3,3-dimethylindolin-l-yl)propanenitrile (105 mg). LCMS m/z = 201.2 [M+l]+; NMR (400 MHz, CDC13) delta ppm 1.26 (s, 3H), 1.40 (s, 3H), 1.63 (d, J = 7.3 Hz, 3H), 3.05 (d, J = 8.2 Hz, 1H), 3.25 (d, J = 8.2 Hz, 1H), 4.57 (q, J = 7.3 Hz, 1 H), 6.57 (d, J = 7.9 Hz, 1H), 6.83-6.87 (m, 1H), 7.06 (dd, J1=7.4 Hz, J2= 0.8 Hz, 1H), 7.12-7.16 (m, 1H).
