Reaction Steps

A solution of 8-methoxy-4-methyl-2-methylsulfanyl-3,4-dihydro-quinazoline hydroiodide (610 mg, 1.7 mmol) in a mixture of acetonitrile (6 ml) and aqueous ammonia (25%, 1.2 ml) was heated in a sealed tube on a shaker for 48 h at 80° C. The title compound (158 mg, 46%, MS: m/e=192.1 [M+H+]) was isolated from the reaction mixture by preparative, reverse-phase HPLC (YMC CombiPrep C18 column 50×20 mm, solvent gradient 1-99% CH3CN in 0.05% triethylamine (aq) over 5.0 min, λ=230 nm, flow rate 40 ml/min) as a solid.
