Procedure

A suspension of isoindoline (0.1 g, 0.839 mmol) and N-ethyl-N-isopropylpropan-2-amine (0.219 ml, 1.259 mmol) in acetonitrile (2.80 ml) was treated with N-methylpyrrolidine (2.80 ml). The solution was cooled to 0° C. and 1-(chloromethyl)-4-isocyanatobenzene (0.155 g, 0.923 mmol) was added. After stirring for 2 hours at 0° C., the reaction was treated with a solution of N-methyl-1-phenylmethanamine (0.102 g, 0.839 mmol) in 0.5 mL acetonitrile. The reaction was stirred at 0° C. for 5 minutes and at ambient temperature for 30 minutes. The reaction was treated with water and the mixture was stirred for 4 hours. The suspension was filtered and the solid collected was washed with water and dried under vacuum to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 8.31 (s, 1H), 7.56-7.49 (m, 2H), 7.40-7.28 (m, 8H), 7.27-7.19 (m, 3H), 4.76 (bs, 4H), 3.47 (s, 2H), 3.43 (s, 2H), 2.06 (s, 3H); MS (ESI(+)) m/e 372 (M+H)+.
