Reaction Steps

Methylamine (2.0 M in methanol, 40 mL, 80 mmol) was added to 5-bromo-2-chloropyrimidine (5.6 g, 29.0 mmol) in a sealable reaction vessel. After allowing to vent for a few minutes, the vessel was sealed, placed behind a safety shield and heated in a 115° C. oil bath for 48 hours. Upon cooling the volatiles were removed in vacuo. The material was dissolved in CH2Cl2 (200 mL) and washed with 1M NaOH (40 mL). The aqueous layer was extracted further with CH2Cl2 (2×50 mL). The combined organics were dried over MgSO4, filtered and concentrated yielding an off white solid (5.1 g, 93%). LCMS (m/z): 188.0/190.0 (MH+).
