Process for the preparation of 4-oxaamines

Preparation of 4-alkoxyalkylamines of formula (I) comprises reacting a 1,3-dioxane of formula (II) with hydrogen and ammonia at 0.1-35 MPa and 40-500 degrees C in the presence of a hydrogenation catalyst. R1, R2, R4, R5 = H, 1-18C alkyl, 2-18C alkenyl, 2-18C alkynyl, 5-8 C cycloalkyl, 5-8 C cycloalk...
