Reaction Steps

A suspension of methyl 4-chloroquinazoline-8-carboxylate (7.18 g, 32.25 mmol) in acetonitrile (70 mL), was treated with N,N-diisopropylethylamine (21.69 g, 167.81 mmol, 5 eq), followed by (1R)-1-(3-nitrophenyl)ethanamine hydrochloride (6.80 g, 33.56 mmol). The suspension was warmed to 45° C. and stirred for 4 h. The reaction mixture was slowly added to water (1000 mL) to precipitate an off-white solid. The solid was filtered to get 8.52 g (24.18 mmol, 75%). LCMS: (M+1) 353.
