Hydrochloric Acid → 5-(4-(4-Benzyloxy-phenylamino)-7-fluoro-quinazolin-6-yl)-furan-2-carbaldehyde hydrochloride

Participants

Reaction Steps

Prepared according to Procedure C from a stirred solution of (4-benzyloxyphenyl)-(6-(5-(1,3-dioxolan-2-yl)-furan-2-yl)-7-fluoro-quinazolin-4-yl)-amine (0.51 grams, 1.1 mmol) in 20 ml of THF was added 5 ml of 1 N HCl. After stirring for 90 minutes, the resultant suspension was filtered and washed with diethyl ether (200 ml) to yield, after drying under vacuum, a yellow solid (0.32 grams, 61% yield). δ1H NMR (400 MHz, DMSO-6) 11.52(s, 1H), 9.70(s, 1H), 9.25(d, 1H), 8.76(s, 1H), 7.76(m, 2H), 7.55(d, 2H), 7.45(d, 2H), 7.33(m, 4H), 7.11(d, 2H), 5.14(s, 2H). ESI-MS m/z 440(M+1).
