With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.165253-29-2,3-(Bromomethyl)tetrahydrofuran,as a common compound, the synthetic route is as follows.

PREPARATION 10 Sodium Tetrahydrofuran-3-ylmethanesulfonate Sodium sulfite heptahydrate (6.10 g) was added to a solution of 3-(bromomethyl)tetrahydrofuran (2.0 g) [see Preparation 9] in 1,4-dioxane (9 ml) and water (9 ml). The reaction mixture was then heated under reflux and stirred for 18 hours, cooled and the solvent removed under reduced pressure. The resulting solid was dissolved in water and concentrated to a low volume. The solid formed was then collected to afford sodium tetrahydrofuran-3-ylmethanesulfonate (1.30 g) as a white solid. 1H-NMR (D2O) delta: 3.95 (1H, m), 3.80-3.60 (2H, m), 3.45 (1H, m), 3.00 (2H, m), 2.60 (1H, m), 2.20 (1H, m), 1.65 (1H, m)., 165253-29-2

To the above was added 3-(bromomethyl)tetrahydrofuran (0.103 g) and the reaction mixture heated at 500C, overnight. The reaction mixture was quenched with water (25 ml.) and extracted into ethyl acetate (3 times, 100 ml. combined total volume). The combined organic phase was separated and passed through a hydrophobic frit to dry. The organic phase was stripped to give a gum which was purified by Ci8 reverse phase chromatography using water (containing 0.1percent formic acid)-acetonitrile (containing 0.05percent formic acid) as eluant (20-60percent) to afford the title compound as a white solid (97mg).

The reaction mixture was diluted with water (10 mL) and extracted with EtOAc (2 x 20 mL). The organic phase was combined, washed with brine (10 mL), passed through a hydrophobic frit and evaporated to dryness. The crude product mixture was purified by prep HPLC (high pH) to give the desired product (14 mg, 0.03 mmol, 12percent) as an off-white powder.This compound was prepared according to Example 465 using Lambda/-[1 – (fluoromethyl)cyclopropyl]-3-[(3-methylisoxazol-5-yl)methyl]-2,4-dioxo-1 1H-quinazoline-6- sulfonamide (100 mg, 0.245 mmol) and 3-(bromomethyl)tetrahydrofuran (60 muIota_, 0.538 mmol). The reaction mixture was heated by microwave irradiation to 120 ¡ãC for 2 h. This afforded the desired product (21 mg, 0.042 mmol, 25percent) as a beige powder, 165253-29-2
