Procedure

A mixture of methyl 2-methyl-5-nitrobenzyl ether (12 g, 0.066 M), methoxyacetone [20 g (used as solvent)], 2-naphthalenesulfonic acid (0.3 g) and 5% Pt/C (0.7 g) is shaken on a Parr hydrogenator maintaining the temperature below 40° with external cooling. The theoretical amount of hydrogen (0.26 M) is consumed and further uptake ceases after 2 hours.
