Procedure
To 4-(2,3-epoxypropoxy)-5,6,7,8-tetrahydronapthaldehyde (2.4 gms) is added tert.-butylamine (15 ml.). The resulting solution is heated at 45° C. for 15 hours. The excess tert.-butylamine is removed at reduced pressure (20 mm). To the residue is added 30 ml. 6 N hydrochloride acid, and the resulting mixture is refluxed for three hours. The acidic mixture is poured into a saturated solution of sodium carbonate which is heated on a steam bath with nitrogen bubbling through it. The basic mixture is extracted with chloroform, which is dried over anhydrous sodium sulfate, filtered and concentrated to give 2.3 g of 4-(3-tert.butylamino-2-hydroxypropoxy)-5,6,7,8-tetrahydronapthaldehyde as an oil.
