Procedure

A solution of 36 (500 mg, 1.28 mmol) in NMP (7 mL) was cooled to 0° C. and treated with HATU (511 mg, 1.34 mmol) and DIPEA (0.33 mL, 1.92 mmol) followed in 15 min by the addition of aniline (0.14 mL, 1.54 mmol). The reaction mixture was allowed to warm to ambient temperature. After 3 h, the solution was diluted with EtOAc, washed with H2O, 1M HCl, H2O, sat NaHCO3, brine, dried over anhydrous Na2SO4, filtered and concentrated to afford 37 (414 mg) as a white foam that was used without further purification. Mass spectrum, m/z [466.4] (M+H)+.
