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. 6N hydrochloric 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.
