Procedure

To a solution of 7-hydroxy-6-methoxy-4-(2-methylindol-5-ylamino)quinazoline (102 mg, 0.32 mmol), 4-(3-hydroxypropyl)morpholine (70 mg, 0.48 mmol), (prepared as described for the starting material in Example 60), triphenylphosphine (168 mg, 0.64 mmol) in methylene chloride (1 ml) and DMF (0.5 ml) cooled at 4° C. was added a solution of diethyl azodicarboxylate (101 μl; 0.64 mmol) in methylene chloride (0.4 ml). The mixture was stirred for 12 hours at 4° C. and overnight at ambient temperature. The mixture was poured onto a column of silica (IST isolute® 10 g of silica) and was eluted with methylene chloride (15 ml) followed by 5% methanol in methylene chloride (45 ml) followed by 5% methanol (saturated with ammonia) in methylene chloride (30 ml) followed by 10% methanol (saturated with ammonia) in methylene chloride (45 ml) followed by 15% methanol (saturated with ammonia) in methylene chloride (30 ml). The fractions containing the expected product were evaporated to give 6-methoxy-4-(2-methylindol-5-ylamino)-7-(3-morpholinopropoxy)quinazoline (63 mg, 44%).
