Reaction Steps

A mixture of 6-bromo-4-chloro-8-methyl-2-(pyridin-3-yl)quinazoline (200 mg, 0.60 mmol, 1.0 eq.), methylamine (81 mg, 1.20 mmol, 2.0 eq.) and Et3N (0.2 mL) in i-PrOH (10 mL) was stirred at 85° C. overnight. The resultant yellow precipitate was collected to afford 125 mg of vi-t as a beige solid (63.4%). LCMS m/z=328.8, 330.8 (M+1-1) (Method B) (retention time=1.95 min).
