실험 절차

A solution of 2-amino-5-bromopyrimidine (0.27 g, 1.55 mmole), N-methyl-N-(1-methyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)acrylamide (0.5 g, 2.33 mmole), Pd(OAc)2 (0.037 g, 0.163 mmole), P(o-tolyl)3 (0.085 g, 0.28 mmole), and (i-Pr)2NEt (0.42 mL, 2.33 mmole) in propionitrile (20 mL) was degassed then heated to reflux. After 18 hr the mixture was cooled to RT and concentrated. Flash chromatography on silica gel (10% MeOH/CH2Cl2) gave the title compound (0.100 g, 18%): MS (ES) m/e 363 (M+H)+.
