Solution
Step 1 (benzoylation): the primary amine is acylated by benzoyl chloride; NaOH removes the HCl formed.
C6H11CH2NH2 + C6H5COCl NaOH C6H11CH2NHCOC6H5 + HCl
[A] = N-(cyclohexylmethyl)benzamide (an amide)
Step 2: LiAlH4 reduces the amide group -CO-NH- to -CH2-NH- (reduction of amides to amines):
C6H11CH2NHCOC6H5 [H2O]LiAlH4 C6H11CH2NHCH2C6H5
[B] is the secondary amine N-benzyl-1-cyclohexylmethanamine:
