Versuchsvorschrift

Prepared in a similar manner to Procedure D from 5-(4-(4-benzyloxy-phenylamino)-7-methoxy-quinazolin-6-yl)-furan-2-carbaldehyde hydrochloride(78 mg, 0.16 mmol), 2-methanesulphonylethylamine(33 mg, 0.27 mmol), acetic acid(15 mg, 0.25 mmol) and triethylamine(18 mg, 0.18 mmol) in 3 ml of 1,2-dichloroethane added to sodium triacetoxyborohydride(102 mg, 0.48 mmol) portionwise over a two day period. The reaction mixture was stirred four days and then partitioned between 10 ml of 0.5M NaHCO3 solution and 50 ml of ethyl acetate. The organic solution was dried with Na2SO4 and concentrated in vacuo. The residue was chromatographed on silica gel with methanol/methylene chloride(1:49 to 2:48). The resulting solid was crystallized from a small volume of ethyl acetate, suspended in ether and filtered to give 43 mg of product as a pale yellow solid. δ1H NMR (400 MHz, DMSO-d6) 9.78(s, 1H), 8.73(s, 1H), 8.42(s, 1H), 6.64(d, 2H), 7.47(m, 2H), 7.40(m, 2H), 7.33(m, 1H), 7.25(s, 1H), 7.04(d, 2H), 6.98(d, 1H), 6.46(d, 1H), 5.12(s, 2H), 4.04(s, 3H), 3.86(s, 2H), 3.28(t, 2H), 3.01 (s, 3H), 2.99(t, 2H).
