As the paragraph descriping shows that 4677-20-7 is playing an increasingly important role.

4677-20-7, 4-(2-Bromoethyl)tetrahydropyran is a Tetrahydropyrans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 7: 6-Amino-2-butylamino-9-r2-(tetrahvdro-2H-pyran-4-yl)ethyll-7,9-dihvdro- 8H-purin-8-one To a solution of /V2-butyl-8-methoxy-9H-purine-2,6-diamine trifluoroacetic acid salt (100 mg) in dry N,N-dimethylformamide (1 ml) at room temperature and under nitrogen was added potassium carbonate (158 mg) in one go. The reaction was stirred at 6O C for 1.5 hours and then cooled to 5O C. A solution of 4-(2- bromoethyl)tetrahydro-2H-pyran (60 mg) in dry N,N-dimethylformamide (0.5 ml) was added in one go and the reaction heated at 5O C overnight. The reaction was diluted with ethyl acetate (15 ml) and washed with water (5 ml). The organic layer was separated and concentrated in vacuo. The product was purified by C18 reverse phase chromatography using water (0.1% formic acid)-acetonitrile (0.05% formic acid) as eluant (20-60%) to afford a yellow viscous oil (47mg) that was dissolved in dry methanol (4 ml) at room temperature and under nitrogen was added 4.0M hydrogen chloride in 1 ,4-dioxane (0.8 ml) in one go. The reaction was left to stir at room temperature overnight. The reaction was neutralised by the addition of 2.0M sodium hydroxide solution and concentrated in vacuo. The residue was taken up in water (5 ml) and the solid filtered and dried in vacuo (60C) for 30 minutes. This afforded the title compound as a beige solid (23mg). MS calcd for (C16H26N6O2)+ = 334 MS found (electrospray): (M+H)+ =3351H NMR ((CDa)2SO): delta 9.78 (1 H, s), 6.08-6.21 (3H, br. s), 3.80 (2H, m), 3.65 (2H, t), 3.21 (2H, m), 3.16 (2H, m), 1.66 (2H, m), 1.57 (2H, m), 1.36-1.49 (3H, m), 1.29 (2H, m), 1.13 (2H, m), 0.88 (3H, t)., 4677-20-7
