4-[1-hydroxy-2-(propan-2-ylamino)ethyl]benzene-1,2-diol

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: One part by weight of isoproterenol hydrochloride and 4 parts by weight of dextrin (DE 10) were added with 20 parts by weight of water, and, similarly as in Example A-1 the resultant mixture was subjected to a saccharide-transfer reaction and glucoamylase reaction, purified by gel chromatography, concentrated and pulverized to obtain a white product of α-glucosyl isoproterenol in the yield of about 35% against the weight of the material isoproterenol, d.s.b. purified by gel chromatography concentrated

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: One part b7 weight of isoproterenol hydrochloride and 4 parts by weight of dextrin (DE 10) were added with 20 parts by weight of water, and, similarly as in Example A-1 the resultant mixture was subjected to a saccharide-transfer reaction and glucoamylase reaction, purified by gel chromatography, concentrated and pulverized to obtain a white product of α-glucosyl isoproterenol in the yield of about 35% against the weight of the material isoproterenol, d.s.b. purified by gel chromatography concentrated
