実験手順
NaH (60% in mineral oil, 16 mg, 0.39 mmol) was added in one portion to a mixture of 9H-purin-6-ylamine (49 mg, 0.36 mmol) in DMF (5 mL) at RT. After 5 min stirring, a solution of methanesulfonic acid 3-o-tolylbenzo[b]thiophen-2-ylmethyl ester from Example 27 (100 mg, 0.30 mmol) in DMF (1 mL) was added dropwise and stirring at RT was continued for 19 h. The reaction mixture was then quenched by addition of water and a solid formed. The precipitated was collected by filtration and was purified by column chromatography (Si—PCC, gradient 0-10% MeOH in EtOAc) affording 167 as a white solid (75 mg, 67%). LCMS: RT 4.13 min [M+H]+ 372.1. 1H NMR (DMSO, 400 MHz): δ 8.11 (1H, s), 7.96-7.88 (2H, m), 7.45-7.30 (6H, m), 7.23 (2H, s), 7.12-7.07 (1H, m), 5.46 (1H, d, J=16.2 Hz), 5.38 (1H, d, J=16.2 Hz), 1.99 (3H, s)
