Sodium sulfate decahydrate → 5-(N-methyl-3-tert-butoxycarbonylaminopropyl)-1,3-bis-(hydroxymethyl)-benzene

Participants

Reaction Steps

To a cooled solution (−5° C.) of 5-(N-methyl-3-tert-butoxycarbonylaminopropyl)-benzene-1,3-dicarboxylic acid diethyl ester (100 mg) in tetrahydrofuran (2 mL) was slowly added a 1M solution of lithium aluminium hydride in diethyl ether (0.55 mL). 10 minutes after the end of the addition, sodium sulfate decahydrate was added until gas evolution ceased. The solid was filtered off, washed twice with ethyl acetate and the combined organic solutions were concentrated in vacuo to give 5-(N-methyl-3-tert-butoxycarbonylaminopropyl)-1,3-bis-(hydroxymethyl)-benzene (66.8 mg) as a viscous oil:
