Yield	Reaction Conditions	Operation in experiment
100%	With hydrogenchloride; In tetrahydrofuran; methanol;	Reference Example 13-1 (2,3-dihydrobenzo[b]furan-5-yl)methanol To a solution of 2,3-dihydrobenzo[b]furan-5-carboxylic acid (1.64 g, 10 mmol) in tetrahydrofuran (10 mL) was added under ice-cooling lithium aluminum hydride (949 mg, 25 mmol) and the mixture was stirred at 60C for 1 h. The reaction mixture was stirred under ice-cooling and methanol and 1N hydrochloric acid were added. The precipitate was filtered off and the mother liquor was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give an almost pure title compound (1.5 g, 100%).
	With lithium aluminium tetrahydride; In tetrahydrofuran; at -8 - 20℃; for 3.0h;	(1) Dissolve dihydrobenzofuran-5-carboxylic acid in anhydrous tetrahydrofuran to obtain solution A. Under temperature of -8 deg.C ~ -6 deg.C, Dropwise adding lithium aluminum hydride to solution A to obtain reaction system A, Warm reaction system A to room temperature uniformly, React for 3h under stirring conditions, Then placed in an ice-water bath to dropwise add ice-water to quench until no bubbles are generated. Add tetrahydrofuran solvent, wash the filtrate 3 times with dichloromethane, and then wash the filtrate with saturated brine. Filter and distill off the solvent under reduced pressure to obtain dihydrobenzofuran-5-methanol; where the mass-volume ratio of dihydrobenzofuran-5-carboxylic acid to anhydrous tetrahydrofuran in reaction system A is 1:20, The molar ratio of hydrobenzofuran-5-carboxylic acid to lithium aluminum hydride is 1: 2.5; the drop acceleration rate of lithium aluminum hydride is 1 g / min;
