For alkyl addition steps I always just draw an arrow with a '1.NaNH2' on the top and a '2. alkyl halide' on the bottom, so in the beginning when we first started doing these synthesis problems I had to remind myself that the numbers were necessary because it wasn't a concerted reaction - one had to occur before the other. So the way you drew it out makes it really clear to see what is happening in those first couple of steps. Ron Bhttps://www.blogger.com/profile/15148292721402122851noreply@blogger.com
