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-d6) 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).
