実験手順

A suspension of 3-(2-bromo-4-nitrophenyl)-1,3-dihydroquinazoline-2,4-dione (0.18 g, 0.5 mmol) and tin (II) chloride dihydrate (0.45 g, 2.0 mmol) in ethyl acetate (5 mL) was heated at 70° C. for 4 hr. The reaction mixture was then cooled, mixed with Celite, made basic with 4N NaOH (3 mL), filtered through Celite, and concentrated in vacuo to give the desired compound (0.155 g, 94%). ES-MS (M+H)+=332, 334 (Br).
