Procedure
4-(2,4-Diamino-pyrimidin-5-ylmethyl)-6-ethoxy-3′-fluoro-4′-morpholin-4-ylmethyl-biphenyl-2-ol (250 mg, 0.55 mmol) are [sic] suspended in 11 ml tetrahydrofuran, 0.5 g powdered molecular sieve are added and the mixture is stirred for 15 minutes at room temperature. Potassium tert-butylate (93 mg; 0.83 mmol) is added and the suspension is stirred again for 1 hour at room temperature. The beige suspension is then cooled to −20° C., and N,N-dimethylsulphamoyl chloride (158 mg; 1.1 mmol) is added. The reaction mixture is stirred for 4 hours at 0° C. and 2 hours at 10° C and then concentrated. The residue is chromatographed over silica gel with methylene chloride/MeOH (99:1). 151 mg (49%) dimethylsulphamic acid 4-(2,4-diamino-pyrimidin-5-ylmethyl)-6-ethoxy-3′-fluoro-4′-morpholin-4-ylmethyl-biphenyl-2-yl ester are obtained as a light-yellow powder.
