2 hours the reactor is cooled to room temperature and the catalyst is removed by filtration the bulk of the solvent is stripped off while raising the temperature to 90 u00b0 c at 40 mm hg vacuum resulting in a layering of the product the two phase system is treated with 600 ml of toluene and 300 ml of water with mechanical agitation at room temperature the aqueous phase is decanted and the toluene layer vacuum distilled using a six inch vigereaux column collecting the fraction boiling at 138 u00b0 143 u00b0 c at 21 mm hg the yield is 171 grams of 98 7 pure methyl n methylanthranilate which calculates to be 69 of theory the procedure of example i was repeated substantially as described with slight variations as noted to obtain seven additional preparations of the subject compound ______________________________________ dis sol reaction tilledbatch no vent formaldehyde period yield purity______________________________________4707 meoh aqueous 37 5 0 hours 69 0 97 1 64bb4707 79b meoh aqueous 37 4 0 hours 86 6 93 8 4707 82 i proh aqueous 37 3 5 hours 97 0 88 7 4707 133 i proh alcoholic 55 3 0 hours 92 0 92 0 4707 86b i proh aqueous 37 lt 8 0 91 6 hours4707 89b i proh aqueous 37 5 0 hours 74 5 4707 91b meoh aqueous 37 lt 8 0 91 4 94 3 hours______________________________________ undistilled 10 mole.
