Procedure

The other portion of the residue CCH 42006-2 (see preparation of compound 56) was transferred in a 5 mL microwave vial equipped with a magnetic stirrer before addition of diisopropylaminomethyl-polystyrene resin (3 mmol/g, 86 mg, 258 μmol), DMAP (2 mg, 16 μmol) and methanesulfonyl chloride (25 μL, 323 μmol) and the reaction mixture was stirred for 20 min at 100° C. under microwave irradiation. After cooling to RT, the mixture was diluted with CH2Cl2 (30 mL), filtered through cotton wool, then washed with brine (5 mL), dried over Na2SO4, filtered, and concentrated under vacuum. Purification by column chromatography (SiO2, eluent cyclohexane:EtOAc=100:0 to 0:100) gave 4-((2-(ethylamino)-6-methoxyquinolin-3-yl)methyl)-6,7-dimethoxy-1-(methylsulfonamidomethyl)isoquinolin-3-yl methanesulfonate as a pale yellow solid.
