=Objective= Monitor the formation of an aromatic imine by HMR and CMR in CDCl3

=Steps=
 * 1) Make up separate 1 mL of 1M solutions of piperonal and 5-methylfurfurylamine in CDCl3.
 * 2) Take HMRs and CMRs of the aldehyde and amine. Use 5 sec relaxation time and acquire for about 15 mins for the CMR. This should be good enough based on James' results at 1M in methanol.
 * 3) Combine the two solutions into a 1 dram vial and shake vigorously then transfer to an NMR tube.
 * 4) Take HMR at 5, 10 and 20 minutes after mixing.
 * 5) Take CMR at 25 min after mixing.
 * 6) Take HMR at 40 min after mixing.
 * 7) Take CMR at 45 min after mixing.
 * 8) Take HMR at 80 mins after mixing.
 * 9) Take CMR at 85 mins after mixing.
 * 10) Continue to take NMRs after interval doubling until no more change is observed.

=Variations=
 * 1) Use methanol-d4 instead of CDCl3.
 * 2) Use phenylacetaldehyde instead of piperonal to see the difference with an aliphatic aldehyde. [|We expect the aromatic aldehyde to be slower].
 * 3) Use 30 and 60 sec relaxation times to approach quantitative peak heights in CMR.
