---|---|---|
36% | 2-Hydroxymethyl-thiophene (2.28 g; 20 mmol) is dissolved in tetrahydrofuran (40 ml, dried over a molecular sieve) and the solution is cooled to -78 C. while gassing with argon. A 1.6 M n-butyllithium solution in n-hexane (25 ml; 40 mmol) is slowly added dropwise. The reaction mixture is then allowed to warm to -30 C. and cooled again to -78 C., and a solution of trimethyl borate (6.69 ml; 60 mmol) in tetrahydrofuran (20 ml) is added dropwise in the course of 15 minutes at between -78 and -70 C. After stirring at -78 C. for 2 hours, the mixture is allowed to warm to room temperature and is poured on to water (50 ml), the pH is brought to 3 by addition of a 2 N aqueous hydrochloric acid solution (28 ml), the mixture is extracted with diethyl ether and the extract is washed with a saturated aqueous sodium chloride solution, dried with sodium sulphate, filtered with suction and concentrated. [00267] Yield: 1.1 g (36%) (5-hydroxymethyl-thiophen-2-yl)-boron acid as a brown oil. [00268] MS: 158 (M) |
